  • Adding a column to a data.frame

    - by Susanne Dreisigacker
    I have the data.frame below. I want to add a column that classifies my data according to column 1 (h_no) in that way that the first series of h_no 1,2,3,4 is class 1, the second series of h_no (1 to 7) is class 2 etc. such as indicated in the last column. h_no h_freq h_freqsq 1 0.09091 0.008264628 1 2 0.00000 0.000000000 1 3 0.04545 0.002065702 1 4 0.00000 0.000000000 1 1 0.13636 0.018594050 2 2 0.00000 0.000000000 2 3 0.00000 0.000000000 2 4 0.04545 0.002065702 2 5 0.31818 0.101238512 2 6 0.00000 0.000000000 2 7 0.50000 0.250000000 2 1 0.13636 0.018594050 3 2 0.09091 0.008264628 3 3 0.40909 0.167354628 3 4 0.04545 0.002065702 3

  • Retrieve value of one column in a table

    - by user327094
    Here is my problem: I have 2 tables Accounts and Transaction Logs. in Accounts table, it has column "Amount" which is a base amount of an account. and in Trans Logs table, it also has column "Amount" which is additional (add or minus to the base amount) amount of the account. and I don't know how to retrieve that base amount to edit it, then save it back to the table. That means I need to get a value of the right column by using Acc_No to find. I'm using DataSet, by the way. i think it should go like this: Dim Amount as Decimal Amount = *the code to retrieve the base amount* Amount = Amount + txtAmount.Text *the code to save the new amount back to Accounts table* Thank you!

  • In SQL, how can I count the number of values in a column and then pivot it so the column becomes the

    - by Josh Yeager
    I have a survey database with one column for each question and one row for each person who responds. Each question is answered with a value from 1 to 3. Id Quality? Speed? -- ------- ----- 1 3 1 2 2 1 3 2 3 4 3 2 Now, I need to display the results as one row per question, with a column for each response number, and the value in each column being the number of responses that used that answer. Finally, I need to calculate the total score, which is the number of 1's plus two times the number of 2's plus three times the number of threes. Question 1 2 3 Total -------- -- -- -- ----- Quality? 0 2 2 10 Speed? 2 1 1 7 Is there a way to do this in set-based SQL? I know how to do it using loops in C# or cursors in SQL, but I'm trying to make it work in a reporting tool that doesn't support cursors.

  • How do I take the advantage of the variable column key/value structure of Cassandra

    - by icejade
    If I have to predefine all the columns, how do I take the advantage of the variable column key/value structure of cassandra? If I use update table command, it will insert null for all the rows which don't have that column. This is same as relational DB. For example, for contact column family, I have name, phone, email. I have 100 contacts have all 3 field. Then number 101 contact has skype id which I want to add. If I use insert statement, it won't let me add skypeid since it's not defined in the CF. So I have to run alter statement to change the CF, then all the first 100 contacts will have a null field for each of them.

  • Copy one column over another in a delimited file

    - by user275455
    For instance, I needed to remove column 25 and replace it with a copy of column 22 in a simple csv file with no embedded delimiters. The best I could come up with was the awkward looking: awk -F, '{ for(x=1;x<25;x++){printf("%s,", $x)};printf("%s,",$22);for(x=26;x<59;x++){printf ("%s,", $x)};print $59}' I would expect something like cut -d, -f1-24,23,26-59 to work but cut doesn't seem to want to print the same column two times... Is there a more elegant way to do it using anything typicaly available in a linux shell environment?

  • Computed Column with relationships

    - by Sethery
    I have a table, MapLocation, which has a column and two relationships with tables that have a field that really need to be displayed as a single concatenated value. I was thinking this was a perfect case for a computed column, but not sure how to go about it. MapLocation MaoNo Section _____________________ _____________________ _____________________ MapNoId MapNoId SectionId SectionId MapNumber (int) Section (int) Identifier (nvarchar) LocationName (nvarchar) LocationName = "MapNUmber - SectionNumber - Identifier" ex: 20 - 03 - SW4 How would I write that? I haven't done much with computed columns or concatenating in SQL. Edit: I need an actual computed column that is automatically updated, im looking for the formula. Or is this more of a function/trigger? Its possible, I certainly barely know what I'm doing. The idea is that I dont want to have to do two more server calls and concatenate these values client side.

  • Silverlight DataGrid: Hiding columns using VisualStateManager

    - by Lars Udengaard
    Is it possible to hide a column of a datagrid, without using codebehind? E.g. by using the VisualStateManager? <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" x:Class="Buttons.MainPage" Width="640" Height="480"> <StackPanel x:Name="LayoutRoot" Width="624" HorizontalAlignment="Right" Margin="0,0,8,0" > <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="EditStates"> <VisualState x:Name="ReadOnly" /> <VisualState x:Name="Edit"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ShownInEditMode" Storyboard.TargetProperty="(UIElement.Visibility)" BeginTime="00:00:00" Duration="00:00:00.0010000"> <DiscreteObjectKeyFrame KeyTime="00:00:00"> <DiscreteObjectKeyFrame.Value> <Visibility>Visible</Visibility> </DiscreteObjectKeyFrame.Value> </DiscreteObjectKeyFrame> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <data:DataGrid AutoGenerateColumns="False" ItemsSource="{Binding BBRNumbers}"> <data:DataGrid.Columns> <data:DataGridTextColumn Header="AlwaysShown" Width="80" Binding="{Binding Municipality}" /> <data:DataGridTextColumn Header="ShownInEditMode" Width="73" Binding="{Binding Estate}" Visibility="Collapsed" /> </data:DataGrid.Columns> </data:DataGrid> </StackPanel> Calling the following should then hide the column, but this doesnt work. VisualStateManager.GoToState(this, "Edit", false); Any ideas?

  • Setting the DataGridColumn's dataField based on XML node with the same name

    - by Rie Mino
    I am stuck. Given this XML: <matrix> <row> <column>0.51</column> <column>0.52</column> <column>0.53</column> <column>0.54</column> </row> <row> <column>0.61</column> <column>0.62</column> <column>0.63</column> <column>0.64</column> </row> I am trying to define a DataGrid such that the row nodes will represent new rows in the DataGrid and the column nodes will be used to auto-populate the DataGrid's columns. I am having a problem setting the dataField for each of the DataGridColumn ojects created. The DataGrid is created but the cell values for row 1 are all 0.51 and row 2 are 0.61. What am I doing wrong here?

  • ORDER BY column_name help (via link in HTML table view) (PHP MySQL

    - by Derek
    My output for my table in HTML has several columns such as userid, name, age, dob. The table heading is simply the title of the column name, I want this to be a link, and when clicked, the selected column is sorted in order, ASC, and then DESC (on next click). I thought this was pretty straight forward but I'm having some difficulty. So far, I have produced this, and no output is taken, apart from the URL works by displaying 'users.php?orderby=userid' <?php if(isset($_GET['orderby'])){ $orderby = $_GET['orderby']; $query_sv = "SELECT * FROM users BY ".mysql_real_escape_string($orderby)." ASC"; } //default query else{ $query_sv = "SELECT * FROM users BY user_id DESC"; } ?> <tr> <th><a href="<?php echo $_SERVER['php_SELF']."?orderby=userid";?>">User ID</a></th> Hoefully if I get this working, I can sort the users by D.O.B. next also using the same principles. Does anyone have any ideas?

  • fix a columns width when a list is bound to a datagridview

    - by Andy
    I have a list that I have bound to a datagridview. I want the first column to be a fixed size. The data is bound to the dataGridView and I can't seem to find a way to access an individual colums properties. if I try myDatagridview.colums[0] I get an index out of bounds, since it says the columns count is 0. private DataGridView setUpDataGrid(List<NVRlineVal> _NVRData) { //setup dataGridView DataGridView NVRDataGridView = new System.Windows.Forms.DataGridView(); NVRDataGridView.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize; NVRDataGridView.Dock = System.Windows.Forms.DockStyle.Fill; NVRDataGridView.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill; NVRDataGridView.Location = new System.Drawing.Point(3, 3); NVRDataGridView.Name = "NVRDataGridView" + nvrIndex; NVRDataGridView.RowHeadersWidthSizeMode = System.Windows.Forms.DataGridViewRowHeadersWidthSizeMode.AutoSizeToDisplayedHeaders; NVRDataGridView.Size = new System.Drawing.Size(380, 401); NVRDataGridView.TabIndex = 0; NVRDataGridView.DataSource = _NVRData; var test = NVRDataGridView.Columns; NVRDataGridView.DataMember = "devState"; DataGridViewAutoSizeColumnMode.None; } Any ideas on how to have a fixed column width for only one of these columns, the rest will autosize?

  • How to Get Dictionary<int, string> from Linq to XML Anonymous Object?

    - by DaveDev
    Currently I'm getting a list of HeaderColumns from the following XML snippet: <HeaderColumns> <column performanceId="12" text="Over last month %" /> <column performanceId="13" text="Over last 3 months %" /> <column performanceId="16" text="1 Year %" /> <column performanceId="18" text="3 Years % p.a." /> <column performanceId="20" text="5 Years % p.a." /> <column performanceId="22" text="10 Years % p.a." /> </HeaderColumns> from which I create an object as follows: (admitedly similar to an earlier question!) var performancePanels = new { Panels = (from panel in doc.Elements("PerformancePanel") select new { HeaderColumns = (from column in panel.Elements("HeaderColumns").Elements("column") select new { PerformanceId = (int)column.Attribute("performanceId"), Text = (string)column.Attribute("text") }).ToList(), }).ToList() }; I'd like if HeaderColumns was a Dictionary() so later I extract the values from the anonymous object like follows: Dictionary<int, string> myHeaders = new Dictionary<int, string>(); foreach (var column in performancePanels.Panels[0].HeaderColumns) { myHeaders.Add(column.PerformanceId, column.Text); } I thought I could achieve this with the Linq to XML with something similar to this HeaderColumns = (from column in panel.Elements("HeaderColumns").Elements("column") select new Dictionary<int, string>() { (int)column.Attribute("performanceId"), (string)column.Attribute("text") }).ToDictionary<int,string>(), but this doesn't work because ToDictionary() needs a Func parameter and I don't know what that is / how to implement it, and the code's probably wrong anyway! Could somebody please suggest how I can achieve the result I need? Thanks.

  • transforming 1d (1column) into 5d(5column) matrix through copy paste or other

    Ex. I want to take the column with 12345..... and order 5 columns across as seen. next 5 numbers in column will be next row. However my code creates a 4 row gap in between each successive row. I dont know what additional logic (possibly if then statement) I can embed into do loop to may make it cleaner.

  • how do I concatenate a regex in a bash alias?

    - by Rodreegez
    Hello, I can't for the life of me how to create an alias that will switch to a given project directory. I keep all my projects in a folder called Projects i.e. ~/Project/blog ~/Project/whatever I'd like to have an alias along the lines of p whatever that would equate to cd ~/Project/$1 where $1 is whatever is given to p. I have tried various combinations of alias p="cd ~/Projects/\$1" with all the usual suspects for regex escaping but I can't quite get it. Any ideas?

  • Rename "Event" object in jQuery FullCalendar plug-in

    - by Jeff
    GREAT PLUGIN!!! BUT... choice of word "Event" to mean a "calendar entry" was particularly unfortunate This is a wonderfully well-written plug in, and I've really impressed people here at work with what this thing can do. The documentation is astonishingly thorough and clear. Congratulations to Adam! HOWEVER, this plug-in refers to entries in the calendar as "Events" -- this has caused a lot of confusion in my development team's conversations, because when we use the word "Event" we think of things like onmouseover, click, etc. We would really prefer a term like CalendarEvent or CalendarEntry. I am not all that experienced with jQuery yet, so am wondering if there is a simple way to alias one of those terms to this plug-in's Event/Events object? (I know we could recode the plug-in directly, but our code will then break when we download an update.) Thanks!

  • java generics covariance

    - by soocracy42
    I am having trouble understanding the following article: http://www.ibm.com/developerworks/java/library/j-jtp01255.html Under, Generics are not covariant the author states, Because ln is a List, adding a Float to it seems perfectly legal. But if ln were aliased with li, then it would break the type-safety promise implicit in the definition of li -- that it is a list of integers, which is why generic types cannot be covariant. I can't understand the part where it says "if ln were aliased with li". What does the author means by alias?(reference?). The code snippet above the quoted line seems to illustrate WHAT is illegal in java and not WHY. It would be very helpful to me if somebody could explain with an example. Thanks in advance.

  • Multiple Apps Possible via Launch Services, want to Specify Particular One

    - by Andrew
    Here's the issue: I have a list of App names that I want to launch. They do not include a path (e.g. {"VLC","Microsoft Word"}. I have two different copies of VLC in different directories. I would like Launch Services to ONLY open the one from /Applications/ and not EVER launch from /Applications/AnotherDirectory I want to get the path of these, and test to see what Launch Services wants to launch (via bash with "open" or applescript via "tell _ to launch" or [NSWorkspace launch...]) The only way that I have come up with to test the path of a file about to be launched by launch services is: Applescript: tell application "Finder" to return the (posix path of (path to application "VLC" as alias)) That works fine, but launches the app (which I don't want at all). Suggestions?

  • Auto sizing column in TVirtualStringTree

    - by Larry Lustig
    Climbing the learning mountain of TVirtualTreeView, I'm attempting to create a custom descendant that ensures that, when the control is resized, the width of the last column exactly fills control's width without requiring a horizontal scroll bar. I see a number of items (a method and a number of events) pertaining to "AutoFitColumns", but not documentation covering this feature. Can I use AutoFitColumns to automatically resize my last column and if so, how.

  • WPF ListView groups repeat column headers

I am using the example at http://msdn.microsoft.com/en-us/library/ms754027.aspx which uses an Expander control to display each group. I would like the column headers to appear inside the expander for each group instead of at the top of the ListView.

  • Displaytag table exported header column contains span tags

    - by Lancelot
    Hi, When I export the content of the display tag table I use the data shows up fine, but the header cells are surrounded by html span tags, which is slightly annoying. I can imagine why Displaytag uses spans around the column header's text, but it shouldn't transpose in the exported data I think. Here is my displaytag.properties config related to export: # Export export.amount = list export.decorated = true export.banner=<div id="exportTypes"><span class="label">Export: </span>{0}</div> export.banner.sepchar=&nbsp;| export.types=excel csv xml export.excel=true export.csv=true export.xml=false export.excel.label=xls export.csv.label=csv export.xml.label=xml export.excel.filename=export.xls export.csv.filename=export.csv export.xml.filename=export.xml export.excel.include_header=true export.csv.include_header=true export.xml.include_header=true Here is the displaytag table itself: <display:table class="list sortable" defaultsort="1" export="true" htmlId="contacts" id="row" name="contacts" requestURI=""> <display:setProperty name="export.banner"><div id="exportTypes"><span class="label">Export:</span> {0}</div></display:setProperty> <display:setProperty name="export.csv.filename">CSV</display:setProperty> <display:setProperty name="export.excel.filename">XLS</display:setProperty> <display:setProperty name="basic.msg.empty_list_row"> <tr class="empty"> <td colspan="7">Empty</td> </tr> </display:setProperty> <display:column class="lastName" property="lastName" sortProperty="lastName" headerClass="lastName first" sortable="true" titleKey="Lastname" href="contact/view" paramId="contactId" paramProperty="id" /> <display:column property="firstName" class="firstName" headerClass="firstName" sortable="true" titleKey="FirstName" /> <display:column class="loginName" headerClass="loginName" sortable="true" titleKey="Username" /> </display:table> My problem is when I click export on either the CSV or the XLS format the header row in the generated file looks like this: <span>Last Name</span> <span>First Name</span> <span>Username</span> I really don't want those span tags in there, any way to work around that? Thanks
