  • R : remove columns from dataframe where ALL values are NA

    - by Sophomore
    hello everybody! I'm having some trouble with my huge data frame and couldn't really resolve that question myself: The dataframe has some properties as columns and each row represents one data set. I've done some sanatizing to this dataframe (e.g. get rid of datasets which are not to be included in evaluation). (Whoever might be interested: Beforehand I aggregate around 5000 single text files and put them in a tsv, some of the proerties have a sequence number like "button.pressed.1" ... ""button.pressed.n". Some of the sets excluded had really high numbers for n but got excluded, all sets left have much smaller numbers for n but the property "button.presed.50" is still there and all remaining sets have an NA in that column. Actually its a different property but the example should clarify my intention...) So the question is quite simple (for some sophisticated R pro): I need to get rid of columns where for ALL rows the value is NA. Could someone please help me out? (All I have managed to get rid of columns where at least one NA exists which dropped about half my columns)...

  • Renaming nodes and values with xslt

    - by T.K.
    Hello world, I'm new to xslt, and have a task that I'm not really sure where to go with. I want to rename nodes, but maintain the format all node declarations. In the actual context I'll be applying this to, I'll be doing a series of renames like this, but for the sake of brevity, the sample I've written up only involves renaming one node. I am using XSL 1.0. Input: <variables> <var> <RENAME> a </RENAME> </var> <var RENAME='b'/> <var> <DO_NOT_TOUCH> c </DO_NOT_TOUCH> </var> <var DO_NOT_TOUCH='d'/> </variables> Desired Output: <variables> <var> <DONE> a </DONE> </var> <var DONE='b'/> <var> <DO_NOT_TOUCH> c </DO_NOT_TOUCH> </var> <var DO_NOT_TOUCH='d'/> </variables> My xslt: <xsl:template match="RENAME"> <RENAMED> <xsl:apply-templates select="@*|node()"/> </RENAMED> </xsl:template> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> Current Output <variables> <var> <RENAMED> a </RENAMED> </var> <var RENAME="b"> </var> <var> <DO_NOT_TOUCH> c </DO_NOT_TOUCH> </var> <var DO_NOT_TOUCH="d"> </var> </variables>

    - by shinjuo
    I have a page that I made that is going to be used for retrieving shipping rates from UPS by entering the weight and zip. Everything works fine but what I want to add to it is the ability for the user to choose something on a form and have it update the value in a different form box. I think this is done with javascript. Any suggestions will help.

  • PHP or C# script to parse CSV table values to fill in one-to-many table

    - by Yaaqov
    I'm looking for an example of how to split-out comma-delimited data in a field of one table, and fill in a second table with those individual elements, in order to make a one-to-many relational database schema. This is probably really simple, but let me give an example: I'll start with everything in one table, Widgets, which has a "state" field to contain states that have that widget: Table: WIDGET =============================== | id | unit | states | =============================== |1 | abc | AL,AK,CA | ------------------------------- |2 | lmn | VA,NC,SC,GA,FL | ------------------------------- |3 | xyz | KY | =============================== Now, what I'd like to create via code is a second table to be joined to WIDGET called *Widget_ST* that has widget id, widget state id, and widget state name fields, for example Table: WIDGET_ST ============================== | w_id | w_st_id | w_st_name | ------------------------------ |1 | 1 | AL | |1 | 2 | AK | |1 | 3 | CA | |2 | 1 | VA | |2 | 2 | NC | |2 | 1 | SC | |2 | 2 | GA | |2 | 1 | FL | |3 | 1 | KY | ============================== I am learning C# and PHP, so responses in either language would be great. Thanks.

  • Problem with returning values from a helper method in Rails

    - by True Soft
    I want to print some objects in a table having 2 rows per object, like this: <tr class="title"> <td>Name</td><td>Price</td> </tr> <tr class="content"> <td>Content</td><td>123</td> </tr> I wrote a helper method in products_helper.rb, based on the answer of this question. def write_products(products) products.map { |product| content_tag :tr, :class => "title" do content_tag :td do link_to h(product.name), product, :title=>product.name end content_tag :td do product.price end end content_tag :tr, :class => "content" do content_tag :td, h(product.content) content_tag :td, product.count end }.join end But this does not work as expected. It only returns the last node - the last <td>123</td> What should I do to make it work?

  • How can I change GWT's widget CSS values?

    - by Xorty
    Basically, I like default theme widgets. However, I need to change font size on DecoratedStackPanel widget. I think it should be possible with something like this: decoratedStackPanel.getElement().getStyle().setProperty("fontSize", "12pt"); However, "fontSize" is not valid name for property and I didn't find way how to get all element's properties. Therefore, I don't know correct property name. Any ideas? Please, don't post about inheriting widget or writing custom CSS. I like default one but the font size. This should be possible afaik.

  • Problem: writing parameter values to data driven MSTEST output

    - by Shubh
    Hi, I am trying to extract some information about the parameter variants used in an MSTEST data driven test case from trx file. Currently, For data driven tests, I get the output of same testcase with different inputs as a sequence of tags , but there is no info about the value of the variants. Example: Suppose we have a [data driven]TestMethod1() and the data rows contain variations a and b. There are two variations a=1,b=2 for which the test passes and a=3,b=4 for which the test fails. If we can output the info that it was a=1,b=2 which passed and a=3 b=4 which failed in the trx file; the output will be meaningful. Better information about test case runs from the output file alone(without any dependencies). Investigating the test failure without rerunning the whole set If the data rows change in data source(now a=1,b=2 pass and a=5,b=6 fail) , easy to decipher that the errors are different; although the fail sequence is still the same(row 0 pass row 1 fail but now row1 is different) Has any of you gone through a similar problem? What did you follow? I tried to put the parameter value information in the Description attribute of TestMethod, it didnt work. Any other methods you think can work too? thanks, Shubhankar

  • string representation of enum values

    - by robUK
    Hello, gcc 4.4.2 c89 I have the following enum: enum drop_options_e { drop_ssm, drop_snm, drop_ssb }; I am just wondering that is the best way to get the string representation value from the enum. So basically, instead of returning the value of 0 for drop_ssm, I could get the 'drop_ssm' instead. Many thanks for any advice,

  • Using numeric values to select item from a dropdown box with JavaScript

    - by Shyam
    Hi, I have a multitude of dropdown boxes within my webpage. One of these dropdown boxes is used for a single selected value out of a list of options. <SELECT id="Box0" name=""> <OPTION value="0">none</OPTION> <OPTION value="1">first</OPTION> <OPTION value="2">second</OPTION> </SELECT> How can I add an event to this section, so when it is in focus, I could use numeric keys like 1,2.. to select an option instead of using the mouse or arrow keys for selecting an option? For clarification: if I press "1" on my keyboard, the selected value would become "first", with "2" the selected value becomes "second". I choose not to use a library/framework such as JQuery/Mootools. Thanks,

  • Passing get values mangles my urls

    - by SibLiant
    Just upgraded from 1.3 to 2.0.3 and I'm trying to migrate all the changes. I'm noticing that the following line echo $this->Html->link('Quote', array('controller'=>'crm_quotes', 'action'=>'index', $lead['id'].'/'.$crmContact['CrmContact']['id']), null); builds the url "/crm_quotes/index/15/21". When I click the link I'm taken to url: "/crm_quotes/index/15%2F212 so it's replacing the characters with the html # but it's ultimately breaking the link. When I manually edit the URL to the correct one: "/crm_quotes/index/15/21" the page loads. Can someone enlighten me? Should I be using the url function rather than link? I have a lot of pages that need multiple parameters passed in the url. I was using named parameters but after reading some comments by Mark Story I decided to stop the named parameters as he hinted at their possible removal from future versions.

  • Looping through values in NSDictionary throws fault

    - by jud
    I have a plist file that I am loading into an NSDictionary *setDictionary that contains a set of fields, pictureDesc1, pictureDesc2, etc. Once the NSDictionary is loaded, I can retrieve a value using [setDictionary objectForKey:@"pictureDesc1"]; But I cannot do a loop like this: for (int i=1; i<=numberOfPictures; i++) { NSString *keyName = [NSString stringWithFormat:@"pictureDesc%d",i]; NSString *description = [NSString stringWithFormat:@"%@", [setDictionary objectForKey:keyName]]; } Is there a different way to dynamically call keys from within an NSDictionary?

  • Why does PHP overwrite values when I iterate through this array twice (by reference, by value)

    - by jeremy
    If I iterate through an array twice, once by reference and then by value, PHP will overwrite the last value in the array if I use the same variable name for each loop. This is best illustrated through an example: $array = range(1,5); foreach($array as &$element) { $element *= 2; } print_r($array); foreach($array as $element) { } print_r($array); Output: Array ( [0] = 2 [1] = 4 [2] = 6 [3] = 8 [4] = 10 ) Array ( [0] = 2 [1] = 4 [2] = 6 [3] = 8 [4] = 8 ) Note that I am not looking for a fix, I am looking to understand why this is happening. Also note that it does not happen if the variable names in each loop are not each called $element, so I'm guessing it has to do with $element still being in scope and a reference after the end of the first loop.
