• Cannot get new product attribute in grid display

  - by russjman

  I added a new attribute to my products(a boolean "yes/no" field). It is a variable to enable/disable the price from displaying on the product detail page, and grid view. I managed to get it work on the product info page. But on product grid page I cant seem to access that variable. Specifically, the template i am working with is catalog/product/price.phtml. From what i can tell, the price is being displayed by the same group of if-statements on both the product detail page, and grid page. This has me confused because i cant find any code on that template to handle multiple products, just a bunch of nested if statements. this is how im attempting to access this new variable using $_displayPrice. on line 36 of catalog/product/price.html <?php $_product = $this->getProduct(); ?> <?php $_id = $_product->getId() ?> <?php $_displayPrice = $_product->getDisplayPrice() ? "Yes" : "No"; echo $_displayPrice;?> What has me further confused is that when display $_product-getData(), my new variable isn't anywhere among that data. thanks in advance

• SSIS - How do I use a resultset as input in a SQL task and get data types right?

  - by thursdaysgeek

  I am trying to merge records from an Oracle database table to my local SQL table. I have a variable for the package that is an Object, called OWell. I have a data flow task that gets the Oracle data as a SQL statment (select well_id, well_name from OWell order by Well_ID), and then a conversion task to convert well_id from a DT_STR of length 15 to a DT_WSTR; and convert well_name from a DT_STR of length 15 to DT_WSTR of length 50. That is then stored in the recordset OWell. The reason for the conversions is the table that I want to add records to has an identity field: SSIS shows well_id as a DT_WSTR of length 15, well_name a DT_WSTR of length 50. I then have a SQL task that connects to the local database and attempts to add records that are not there yet. I've tried various things: using the OWell as a result set and referring to it in my SQL statement. Currently, I have the ResultSet set to None, and the following SQL statment: Insert into WELL (WELL_ID, WELL_NAME) Select OWELL_ID, OWELL_NAME from OWell where OWELL_ID not in (select WELL.WELL_ID from WELL) For Parameter Mapping, I have Paramater 0, called OWell_ID, from my variable User::OWell. Parameter 1, called OWell_Name is from the same variable. Both are set to VARCHAR, although I've also tried NVARCHAR. I do not have a Result set. I am getting the following error: Error: 0xC002F210 at Insert records to FLEDG, Execute SQL Task: Executing the query "Insert into WELL (WELL_ID, WELL_NAME) Select OWELL..." failed with the following error: "An error occurred while extracting the result into a variable of type (DBTYPE_STR)". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly. I don't think it's a data type issue, but rather that I somehow am not using the resultset properly. How, exactly, am I supposed to refer to that recordset in my SQL task, so that I can use the two recordset fields and add records that are missing?

• Improving the performance of XSL

  - by Rachel

  I am using the below XSL 2.0 code to find the ids of the text nodes that contains the list of indices that i give as input. the code works perfectly but in terms for performance it is taking a long time for huge files. Even for huge files if the index values are small then the result is quick in few ms. I am using saxon9he Java processor to execute the XSL. <xsl:variable name="insert-data" as="element(data)*"> <xsl:for-each-group select="doc($insert-file)/insert-data/data" group-by="xsd:integer(@index)"> <xsl:sort select="current-grouping-key()"/> <data index="{current-grouping-key()}" text-id="{generate-id( $main-root/descendant::text()[ sum((preceding::text(), .)/string-length(.)) ge current-grouping-key() ][1] )}"> <xsl:copy-of select="current-group()/node()"/> </data> </xsl:for-each-group> </xsl:variable> In the above solution if the index value is too huge say 270962 then the time taken for the XSL to execute is 83427ms. In huge files if the index value is huge say 4605415, 4605431 it takes several minutes to execute. Seems the computation of the variable "insert-data" takes time though it is a global variable and computed only once. Should the XSL be addessed or the processor? How can i improve the performance of the XSL.

• XSLT: need to replace document('')

  - by Daziplqa

  I've the following xslt file: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <!-- USDomesticCountryList - USE UPPERCASE LETTERS ONLY --> <xsl:variable name="USDomesticCountryList"> <entry name="US"/> <entry name="UK"/> <entry name="EG"/> </xsl:variable> <!--// USDomesticCountryList --> <xsl:template name="IsUSDomesticCountry"> <xsl:param name="countryParam"/> <xsl:variable name="country" select="normalize-space($countryParam)"/> <xsl:value-of select="normalize-space(document('')//xsl:variable[@name='USDomesticCountryList']/entry[@name=$country]/@name)"/> </xsl:template> </xsl:stylesheet> I need to replace the "document('')" xpath function, what should I use instead? I've tried to remove it completely but the xsl document doesn't work for me! I need to to so because the problem is : I am using some XSLT document that uses the above file, say document a. So I have document a that includes the above file (document b). I am using doc a from java code, I am do Caching for doc a as a javax.xml.transform.Templates object to prevent multiple reads to the xsl file on every transformation request. I found that, the doc b is re-calling itself from the harddisk, I believe this is because of the document('') function above, so I wanna replace/remove it. Thanks.

• Group variables in a boxplot in R

  - by tao.hong

  I am trying to generate a boxplot whose data come from two scenarios. In the plot, I would like to group boxes by their names (So there will be two boxes per variable). I know ggplot would be a good choice. But I got errors which I could not figure out. Can anyone give me some suggestions? sensitivity_out1 structure(c(0.0522902104339716, 0.0521369824334004, 0.0520240345973737, 0.0519818337359876, 0.051935071418996, 0.0519089404325544, 0.000392698277338341, 0.000326135474295325, 0.000280863338343747, 0.000259631566041935, 0.000246594043996332, 0.000237923540393391, 0.00046732650331544, 0.000474448907808135, 0.000478287273678457, 0.000480194683464109, 0.000480631753078668, 0.000481760272726273, 0.000947965771207979, 0.000944821699830455, 0.000939631071343889, 0.000937186900570605, 0.000936007346568281, 0.000934756220144141, 0.00132442589501872, 0.00132658367774979, 0.00133334696220742, 0.00133622384928092, 0.0013381577476241, 0.00134005741746304, 0.0991622968751298, 0.100791399440082, 0.101946808417405, 0.102524244727408, 0.102920085260477, 0.103232984259916, 0.0305219507186844, 0.0304635269233494, 0.0304161055015213, 0.0303742106794513, 0.0303381888169022, 0.0302996157711171, 1.94268588634518e-05, 2.23991225564447e-05, 2.5756135487907e-05, 2.79997917298194e-05, 3.00753967077715e-05, 3.16270817369878e-05, 0.544701146678523, 0.542887331601984, 0.541632986366816, 0.541005610554556, 0.540617004208336, 0.540315690692195, 0.000453386694666078, 0.000448473414508756, 0.00044692043197248, 0.000444826296854332, 0.000445747996014684, 0.000444764303682453, 0.000127569551159321, 0.000128422491392669, 0.00012933662856487, 0.000129941842982939, 0.000129578971489026, 0.000131113075233758, 0.00684610571790029, 0.00686349387897349, 0.00687468164010565, 0.00687880720347743, 0.00688275579317197, 0.00687822247621936), .Dim = c(6L, 12L)) out2 structure(c(0.0189965816735366, 0.0189995096225103, 0.0190099362589894, 0.0190033523148514, 0.01900896721937, 0.0190099427513381, 0.00192043989797585, 0.00207303208721059, 0.00225931163225165, 0.0024049969048389, 0.00252310364086785, 0.00262940166568126, 0.00195164921633517, 0.00190079923515755, 0.00186139563778548, 0.00184188171395076, 0.00183248544676564, 0.00182492970673969, 1.83038731485927e-05, 1.98252671720347e-05, 2.14794764479231e-05, 2.30713122969332e-05, 2.4484220713564e-05, 2.55958833705284e-05, 0.0428066864455102, 0.0431686808647809, 0.0434411033615353, 0.0435883377765726, 0.0436690169266633, 0.0437340464360965, 0.145288252474567, 0.141488776430307, 0.138204532539654, 0.136281799717717, 0.134864952272761, 0.133738386148036, 0.0711728636959696, 0.072031388688795, 0.0727536853228245, 0.0731581966147734, 0.0734424337399303, 0.0736637270702609, 0.000605277151497094, 0.000617268349064968, 0.000632975679951382, 0.000643904422677427, 0.000653775268094148, 0.000662225067910141, 0.26735354610469, 0.267515415990146, 0.26753155165617, 0.267553498616325, 0.267532284594615, 0.267510330320289, 0.000334158771646756, 0.000319032383145857, 0.000306074699839994, 0.000299153278494114, 0.000293956197852583, 0.000290171804454218, 0.000645975219899115, 0.000637548672578787, 0.000632375486965757, 0.000629579821884212, 0.000624956458229123, 0.000622456283217054, 0.0645188290106884, 0.0651539609630352, 0.0656417364889907, 0.0658996698322889, 0.0660715073023965, 0.0662034341510152), .Dim = c(6L, 12L)) Melt data: group variable value 1 1 PLDKRT 0 2 1 PLDKRT 0 3 1 PLDKRT 0 4 1 PLDKRT 0 5 1 PLDKRT 0 6 1 PLDKRT 0 Code: #Data_source 1 sensitivity_1=rbind(sensitivity_out1,sensitivity_out2) sensitivity_1=data.frame(sensitivity_1) colnames(sensitivity_1)=main_l #variable names sensitivity_1$group=1 #Data_source 2 sensitivity_2=rbind(sensitivity_out1[3:4,],sensitivity_out2[3:4,]) sensitivity_2=data.frame(sensitivity_2) colnames(sensitivity_2)=main_l sensitivity_2$group=2 sensitivity_pool=rbind(sensitivity_1,sensitivity_2) sensitivity_pool_m=melt(sensitivity_pool,id.vars="group") ggplot(data = sensitivity_pool_m, aes(x = variable, y = value)) + geom_boxplot(aes( fill= group), width = 0.8) Error: "Error in unit(tic_pos.c, "mm") : 'x' and 'units' must have length > 0" Update Figure out the error.

• Indentation control while developing a small python like language

  - by sap

  Hello, I'm developing a small python like language using flex, byacc (for lexical and parsing) and C++, but i have a few questions regarding scope control. just as python it uses white spaces (or tabs) for indentation, not only that but i want to implement index breaking like for instance if you type "break 2" inside a while loop that's inside another while loop it would not only break from the last one but from the first loop as well (hence the number 2 after break) and so on. example: while 1 while 1 break 2 'hello world'!! #will never reach this. "!!" outputs with a newline end 'hello world again'!! #also will never reach this. again "!!" used for cout end #after break 2 it would jump right here but since I don't have an "anti" tab character to check when a scope ends (like C for example i would just use the '}' char) i was wondering if this method would the the best: I would define a global variable, like "int tabIndex" on my yacc file that i would access in my lex file using extern. then every time i find a tab character on my lex file i would increment that variable by 1. when parsing on my yacc file if i find a "break" keyword i would decrement by the amount typed after it from the tabIndex variable, and when i reach and EOF after compiling and i get a tabIndex != 0 i would output compilation error. now the problem is, whats the best way to see if the indentation got reduced, should i read \b (backspace) chars from lex and then reduce the tabIndex variable (when the user doesn't use break)? another method to achieve this? also just another small question, i want every executable to have its starting point on the function called start() should i hardcode this onto my yacc file? sorry for the long question any help is greatly appreciated. also if someone can provide an yacc file for python would be nice as a guideline (tried looking on Google and had no luck). thanks in advance.

• I want to request JSON inside of a WordPress page.

  - by gnucom

  Hello Everyone, For the last few hours I've been trying to set up this http://code.google.com/apis/books/docs/dynamic-links.html on a WordPress blog. Google's API sends back a JSON response (which is supposed to be "put" into _GBSBookInfo variable). However, that variable never is assigned so my javascript callback function explodes saying the variable doesn't exist. So far, all of my javascript is in the WordPress header. I tried this outside of WordPress and it works fine. This is the static page: <script src="http://books.google.com/books?bibkeys=0307346609&jscmd=viewapi&callback=response_handler"> This is the handler: function response_handler(data) { var bookInfo = _GBSBookInfo["0307346609"]; // the var that doesn't exist document.getElementById("test123").innerHTML = bookInfo.thumbnail_url; } Thanks for any help in advance, WordPress has been extremely frustrating by limiting so much! If I'm doing anything stupid please say so, I'm a new javascript programmer. EDIT: I've used firebug so far to identify the problem to be: the _GBSBookInfo variable never gets "created" or "exists". I'm not sure how javascript works at this level. Hopefully this helps. ERRORS: Error: _GBSBookInfo is not defined Line: 79

• Populate tableView with more than one array

  - by Ewoods

  The short version: Is there a way to populate one specific row in a tableView with one value from one array, then populate another row in that same tableView with one value from a different array? For example, cell 1 would have the first value from Array A, cell 2 would have the first value from Array B, cell 3 would have the first value from Array C, etc. The long version: I hope this isn't too confusing. I've got an array of names, and then three more arrays with actions associated with those people. For example, the names array has Jim, Bob, and Sue, and then there's an array for eating, reading, and sleeping that records every time each person does one of these things (all of these arrays are populated from a MySQL database). The names array is used to populate a root tableView. Tapping on one of the names brings up a detail view controller that has another tableView that only has three rows. This part is all working fine. What I want to happen is when I tap on a name, it moves to the detail view and the three cells would then show the last event for that person for each of the three activities. Tapping on one of those three events then moves to a new view controller with a tableView that shows every event for that category. For example, if I tapped on Bob, the second page would show the last time Bob ate, read, and slept. Tapping on the first row would bring up a table that showed every time Bob has eaten. So far I've only been able to populate the second tableView with all of the rows from one of the arrays. I need it the other way around (one row from all of the arrays).

• Closures in Ruby

  - by Isaac Cambron

  I'm kind of new to Ruby and some of the closure logic has me a confused. Consider this code: array = [] for i in (1..5) array << lambda {j} end array.map{|f| f.call} => [5, 5, 5, 5, 5] This makes sense to me because i is bound outside the loop, so the same variable is captured by each trip through the loop. It also makes sense to me that using an each block can fix this: array = [] (1..5).each{|i| array << lambda {i}} array.map{|f| f.call} => [1, 2, 3, 4, 5] ...because i is now being declared separately for each time through. But now I get lost: why can't I also fix it by introducing an intermediate variable? array = [] for i in 1..5 j = i array << lambda {j} end array.map{|f| f.call} => [5, 5, 5, 5, 5] Because j is new each time through the loop, I'd think a different variable would be captured on each pass. For example, this is definitely how C# works, and how -- I think-- Lisp behaves with a let. But in Ruby not so much. It almost looks like = is aliasing the variable instead of copying the reference, but that's just speculation on my part. What's really happening?

• Properly populating tables in an Object Relational database

  - by chaosTechnician

  I've got a homework assignment that requires that I use Oracle 10g Express to implement an Object Relational database to track phone billing data. I have a superclass of Communications with subclasses of Call, Text, and Data. I'm hitting a snag with properly populating these tables so that I can find the appropriate data in the various tables. My Types and Tables are declared as such: create type CommunicationType as object ( -- column names here ) not final; create type CallType under CommunicationType ( -- column names here ); create type TextType under CommunicationType ( -- column names here ); create type DataType under CommunicationType ( -- column names here ); create table Communications of CommunicationType ( -- Primary and Foreign key constraints here ); create table Calls of CallType; create table Texts of TextType; create table Datas of DataType; When I try to insert data into one of the subclasses, its entry doesn't appear in the superclass. Likewise if I insert into the superclass, it doesn't show up in the appropriate subclass. For example, insert into Calls values (CallType( -- Values -- )); doesn't show any data in Communications. Nor does insert into Communications values (CallType( -- Values -- )); show anything in Calls. What am I doing wrong?

• Enumerating computers in NT4 domain using WNetEnumResourceW (C++) or DirectoryEntry (C#)

  - by Kevin Davis

  I'm trying to enumerate computers in NT4 domains (not Active Directory) and support Unicode NetBIOS names. According to MSDN, WNetEnumResourceW is the Unicode counterpart of WNetEnumResource which to me would imply that using this would do the trick. However, I have not been able to get Unicode NetBIOS names properly using WNetEnumResourceW. I've also tried the C# rough equivalent DirectoryEntry using the WinNT: provider with no luck on Unicode names either. If I use DirectoryEntry on Active Directory (using the LDAP: provider) I do get Unicode names back. I noticed that during some debugging my code using DirectoryEntry and the WinNT: provider, the exceptions I saw were of type System.Runtime.InteropServices.COMException which tends to make me believe that this is just calling WNetEnumResourceW via COM. This web page implies that for some Net APIs the MS documentation is incomplete and possibly inaccurate which further confuses things. Additionally I've found that using the C# method which certainly results in cleaner, more understandable code also yields incomplete results in enumerating computers in domains\workgroups. Does anyone have any insight on this? Is it possible that computer acting as the WINS server is mangling the name? How would I determine this? Thanks

• Java function changing input

  - by Doodle

  I would like to go from one number to another. For example if I started at 6 and my goal was 10 I want a function that on every pass would bring me from 6 towards 10 or if I had the number 14 and my goal was 9 it would count down from 14 towards 9.So far I have (this is written in Processing a Java Api but there is essentially no difference from regualr Java, draw is just a continuous loop) int x=100; void draw(){ x=towards(x,10); println(x); } int towards(int current ,int target){ if(current!=target){ if (current <target){ current=current+1; } else { current=current-1; } } return current; } this gives me the results I would like but I would like to have everything in side of the towards() function. When I replace X with a variable it of course resets it self to the static variable. To sum it up how can I pass a variable to a function and have that variable thats been passed change on every subsequent pass. I have looked into recursion as a solution but that of just brings me to a final solution. I can pass the count to an array but wouldn't like to do that either.

• Drupal theme preprocess function - primary links and suckerfish menus

  - by slimcady

  I have a preprocess function that works fine when the menu is single level list. However I would like it to work w/ suckerfish menus. I want to add a class to the top level menu item so that I can style it. This is the code I used for the single level menu: function cti_flex_preprocess_page(&$vars, $hook) { // Make a shortcut for the primary links variables $primary_links = $vars['primary_links']; // Loop thru the menu, adding a new class for CSS selectors $i = 1; foreach ($primary_links as $link => $attributes){ // Append the new class to existing classes for each menu item $class = $attributes['attributes']['class'] . " item-$i"; // Add revised classes back to the primary links temp variable $primary_links[$link]['attributes']['class'] = $class; $link['title'] = '<span class="hide">' . check_plain($link['title']) . '</span>'; $i++; } // end the foreach loop // reset the variable to contain the new markup $vars['primary_links'] = $primary_links; } I've been trying to use the menu_tree() function to no avail, for example: function cti_flex_preprocess_page(&$vars, $hook) { // Make a shortcut for the primary links variables $primary_links = $vars['primary_links']; // Loop thru the menu, adding a new class for CSS selectors $i = 1; foreach ($primary_links as $link => $attributes){ // Append the new class to existing classes for each menu item $class = $attributes['attributes']['class'] . " item-$i"; // Add revised classes back to the primary links temp variable $primary_links[$link]['attributes']['class'] = $class; $link['title'] = '<span class="hide">' . check_plain($link['title']) .

• Slope requires a real as parameter 2?

  - by Dave Jarvis

  Question How do you pass the correct value to udf_slope's second parameter type? Attempts CAST(Y.YEAR AS FLOAT), but that failed (SQL error). Y.YEAR + 0.0, but that failed, too (see error message). slope(D.AMOUNT, 1.0), failed as well Error Message Using udf_slope fails due to: Can't initialize function 'slope'; slope() requires a real as parameter 2 Code SELECT D.AMOUNT, Y.YEAR, slope(D.AMOUNT, Y.YEAR + 0.0) as SLOPE, intercept(D.AMOUNT, Y.YEAR + 0.0) as INTERCEPT FROM YEAR_REF Y, DAILY D Here, D.AMOUNT is a FLOAT and Y.YEAR is an INTEGER. Create Function The slope function was created as follows: CREATE AGGREGATE FUNCTION slope RETURNS REAL SONAME 'udf_slope.so'; Function Signature From udf_slope.cc: double slope( UDF_INIT* initid, UDF_ARGS* args, char* is_null, char* is_error ) Example Usages Reading the fine manual reveals: UDF intercept() Calculates the intercept of the linear regression of two sets of variables.

• C++ converting back and forth from derived and base classes

  - by user127817

  I was wondering if there is a way in C++ to accomplish the following: I have a base class called ResultBase and two class that are Derived from it, Variable and Expression. I have a few methods that do work on vector<ResultBase> . I want to be able to pass in vectors of Variable and Expression into these methods. I can achieve this by creating a vector<ResultBase> and using static_cast to fill it with the members from my vector of Variable/Expression. However, once the vector has run through the methods, I want to be able to get it back as the vector of Result/Expression. I'll know for sure which one I want back. static_cast won't work here as there isn't a method to reconstruct a Variable/Expression from a ResultBase, and more importantly I wouldn't have the original properties of the Variables/Expressions The methods modify some of the properties of the ResultBase and I need those changes to be reflected in the original vectors. (i.e. ResultBase has a property called IsLive, and one of the methods will modify this property. I want this IsLive value to be reflected in the derived class used to create the ResultBase Whats the easiest way to accomplish this?

• Vim: Making Auto-Completion Smarter

  - by Rafid K. Abdullah

  I use ctags, taglist, etc., to have auto completion in Vim. However, it is very limited compared to Visual Studio intellisense or Eclipse auto-completion. I am wondering whether it is possible to tune Vim to: Show auto-completion whenever . or - are typed. But only after some text that might be a variable (e.g. avoid showing auto completion after a number). Show function parameters when ( is typed. Stop removing the auto completion list when some delete all characters after . or -: When I enter a variable name, then press . or - to search for a certain member, I frequently have to delete all the characters I type after the . or -, but this makes Vim hide the auto completion list. I would like to keep it visible unless I press Esc. Showing related auto completion: When I type a variable and press ^X ^O, it usually shows me all the tags in the ctags file. I would like to have it showing only the tags related to the variable. Thanks for the help. EDIT: Some people are voting for this question, but no body seems to know the answer. So just wanted to mention that you don't have to provide a complete answer; partial answers to any of the mentioned points would be good also.

• Protecting my apps security from deassembling

  - by sandis

  So I recently tested deassembling one of my android apps, and to my horror I discovered that the code was quite readable. Even worse, all my variable names where intact! I thought that those would be compressed to something unreadable at compile time. The app is triggered to expire after a certain time. However, now it was trivial for me to find my function named checkIfExpired() and find the variable "expired". Is there any good way of making it harder for a potential hacker messing with my app? Before someone states the obvious: Yes, it is security through obscurity. But obviously this is my only option since the user always will have access to all my code. This is the same for all apps. The details of my deactivation-thingy is unimportant, the point is that I dont want deassembler to understand some of the things I do. side questions: Why are the variable names not compressed? Could it be the case that my program would run faster if I stopped using really long variable names, as are my habit?

• How to filter node list based on the contents of another node list

  - by ~otakuj462

  Hi, I'd like to use XSLT to filter a node list based on the contents of another node list. Specifically, I'd like to filter a node list such that elements with identical id attributes are eliminated from the resulting node list. Priority should be given to one of the two node lists. The way I originally imagined implementing this was to do something like this: <xsl:variable name="filteredList1" select="$list1[not($list2[@id_from_list1 = @id_from_list2])]"/> The problem is that the context node changes in the predicate for $list2, so I don't have access to attribute @id_from_list1. Due to these scoping constraints, it's not clear to me how I would be able to refer to an attribute from the outer node list using nested predicates in this fashion. To get around the issue of the context node, I've tried to create a solution involving a for-each loop, like the following: <xsl:variable name="filteredList1"> <xsl:for-each select="$list1"> <xsl:variable name="id_from_list1" select="@id_from_list1"/> <xsl:if test="not($list2[@id_from_list2 = $id_from_list1])"> <xsl:copy-of select="."/> </xsl:if> </xsl:for-each> </xsl:variable> But this doesn't work correctly. It's also not clear to me how it fails... Using the above technique, filteredList1 has a length of 1, but appears to be empty. It's strange behaviour, and anyhow, I feel there must be a more elegant approach. I'd appreciate any guidance anyone can offer. Thanks.

• SPSS - sum of squares change radically with slight model changes in ANOVA??

  - by Pat

  I have noticed that the sum of squares in my models can change fairly radically with even the slightest adjustment to my models???? Is this normal???? I'm using SPSS 16, and both models presented below used the same data and variables with only one small change - categorizing one of the variables as either a 2 level or 3 level variable. Details - using a 2 x 2 x 6 mixed model ANOVA with the 6 being the repeated measure i get the following in the between group analysis ------------------------------------------------------------ Source | Type III SS | df | MS | F | Sig ------------------------------------------------------------ intercept | 4086.46 | 1 | 4086.46 | 104.93 | .000 X | 224.61 | 1 | 224.61 | 5.77 | .019 Y | 2.60 | 1 | 2.60 | .07 | .80 X by Y | 19.25 | 1 | 19.25 | .49 | .49 Error | 2570.40 | 66 | 38.95 | Then, when I use the exact same data but a slightly different model in which variable Y has 3 levels instead of 2 levels I get the following ------------------------------------------------------------ Source | Type III SS | df | MS | F | Sig ------------------------------------------------------------ intercept | 3603.88 | 1 | 3603.88 | 90.89 | .000 X | 171.89 | 1 | 171.89 | 4.34 | .041 Y | 19.23 | 2 | 9.62 | .24 | .79 X by Y | 17.90 | 2 | 17.90 | .80 | .80 Error | 2537.76 | 64 | 39.65 | I don't understand why variable X would have a different sum of squares simply because variable Y gets devided up into 3 levels instead of 2. This is also the case in the within groups analysis too. Please help me understand :D Thank you in advance Pat

• Split node list to parts.

  xml: <mode>1</mode> <mode>2</mode> <mode>3</mode> <mode>4</mode> <mode>5</mode> <mode>6</mode> <mode>7</mode> <mode>8</mode> <mode>9</mode> <mode>10</mode> <mode>11</mode> <mode>12</mode> i need to separate it on parts (for ex. on 4): xslt: <xsl:variable name="vNodes" select="mode"/> <xsl:variable name="vNumParts" select="4"/> <xsl:variable name="vNumCols" select="ceiling(count($vNodes) div $vNumParts)"/> <xsl:for-each select="$vNodes[position() mod $vNumCols = 1]"> <xsl:variable name="vCurPos" select="(position()-1)*$vNumCols +1"/> <ul> <xsl:for-each select="$vNodes[position() >= $vCurPos and not(position() > $vCurPos + $vNumCols -1)]"> <li><xsl:value-of select="."/></li> </xsl:for-each> </ul> </xsl:for-each> this code is written by Dimitre Novatchev - great coder)) but for the number of nodes less then number of parts (for ex. i have 2 modes) this code does not work - it outputs nothing. How it upgrade for that case (without choose construction)?

• C++ STL Map vs Vector speed

  - by sub

  In the interpreter for my experimental programming language I have a symbol table. Each symbol consists of a name and a value (the value can be e.g.: of type string, int, function, etc.). At first I represented the table with a vector and iterated through the symbols checking if the given symbol name fitted. Then I though using a map, in my case map<string,symbol>, would be better than iterating through the vector all the time but: It's a bit hard to explain this part but I'll try. If a variable is retrieved the first time in a program in my language, of course its position in the symbol table has to be found (using vector now). If I would iterate through the vector every time the line gets executed (think of a loop), it would be terribly slow (as it currently is, nearly as slow as microsoft's batch). So I could use a map to retrieve the variable: SymbolTable[ myVar.Name ] But think of the following: If the variable, still using vector, is found the first time, I can store its exact integer position in the vector with it. That means: The next time it is needed, my interpreter knows that it has been "cached" and doesn't search the symbol table for it but does something like SymbolTable.at( myVar.CachedPosition ). Now my (rather hard?) question: Should I use a vector for the symbol table together with caching the position of the variable in the vector? Should I rather use a map? Why? How fast is the [] operator? Should I use something completely different?

• R: building a simple command line plotting tool/Capturing window close events

  - by user275455

  I am trying to use R within a script that will act as a simple command line plot tool. I.e. user pipes in a csv file and they get a plot. I can get to R fine and get the plot to display through various temp file machinations, but I have hit a roadblock. I cannot figure out how to get R to keep running until the users closes the window. If I plot and exit, the plot disappears immediately. If I plot and use some kind of infinite loop, the user cannot close the plot; he must exit by using an interrupt which I don't like. I see there is a getGraphicsEvent function, but it claims that the device is not supported (X11). Anyway, it doesn't appear to actually support an onClose event, only onMouseDown. Any ideas on how to solve this? edit: Thanks to Dirk for the advice to check out the tk interface. Here is the test code that works: require(tcltk) library(tkrplot) ##function to display plot, called by tkrplot and embedded in a window plotIt<-function(){ plot(x=1:10, y=1:10) } ##create top level window tt<-tktoplevel() ##variable to wait on like a condition variable, to be set by event handler done <- tclVar(0) ##bind to the window destroy event, set done variable when destroyed tkbind(tt,"",function() tclvalue(done) <- 1) ##Have tkrplot embed the plot window, then realize it with tkgrid tkgrid(tkrplot(tt,plotIt)) ##wait until done is true tkwait.variable(done)

• SSIS Expressions - EvaluateAsExpression Problem

  - by Randy Minder

  In a Data Flow, I have an Derived Column task. In the expression for one of the columns, I have the following expression: [siteid] == "100" ? "1101" : [siteid] == "110" ? "1001" : [siteid] == "120" ? "2101" : [siteid] == "140" ? "1102" : [siteid] == "210" ? "2001" : [siteid] == "310" ? "3001" : [siteid] This works just fine. However, I intend to reuse this in at least a dozen other places so I want to store this to a variable and use the variable in the Derived Column instead of the hard-coded expression. When I attempt to create a variable, using the expression above, I get a syntax error saying 'siteid' is not defined. I guess this makes sense because it isn't. But how can I get this the expression to work by using a variable? It seems like I need some sort of way to tell it that 'siteid' will be the column containing the data I want to apply the expression to.

• Why ng-hide don't work with custom directives?

  - by javier

  I'm reading the directives section of the developers guide on angularjs.org to refresh my knowledge and gain some insights and I was trying to run one of the examples but the directive ng-hide is not working on a custom directive. Here the jsfiddle: http://jsfiddle.net/D3Nsk/: <my-dialog ng-hide="dialogIsHidden" on-close="hideDialog()"> Does Not Work Here!!! </my-dialog> <div ng-hide="dialogIsHidden"> It works Here. </div> Any idea on why this is happening? Thanks. solution Seems that the variable dialogIsHidden on the tag already make a reference to a scope variable inside the directive and not to the variable in the controller; given that the directive has it's own insolated scope, to make this work it's necesary to pass by reference the variable dialogIsHidden of the controller to the directive. Here the jsfiddle: http://jsfiddle.net/h7xvA/ changes at: <my-dialog ng-hide="dialogIsHidden" on-close="hideDialog()" dialog-is-hidden='dialogIsHidden'> and: scope: { 'close': '&onClose', 'dialogIsHidden': '=' },
