row

问题 I have a dataframe of values and for each value in the dataframe I want to determine if it is within say 10% of any other value in its row. I want to do this generically as I do not know how many columns I will have nor the names of the columns. Some values are NA, if all other values in the row are NA I want to return TRUE. For the actual values which are NA I want to return FALSE. The values are all positive but can be 0. For example say I have the follwoing dataframe dataDF <- data.frame(

问题 I'm trying to change the font color of a row in a datagrid if a certain word is found in a datafield. Is there a simple, inline way to do this? Thanks 回答1: You can override your DataGrid 's drawRowBackground method, and check whether it needs custom background or not. If so, pass the new background color to the super call of this method: protected override function drawRowBackground(s:Sprite, rowIndex:int, y:Number, height:Number, color:uint, dataIndex:int):void { if ((dataProvider[dataIndex]

问题 I am looking for a solution for a JTable where I can vary the number of columns in each row, but where the size (in pixels) of the row is constant. I found stackoverflow referencing so far only dead-links to an old solution: JTable with varying number of columns per row Is there a newer better way to do it now ? If so, what? If not, does anyone know what the old solution was? thanks. 回答1: Does anyone know what the old solution was? The examples, which appear to have been created for a Swing

问题 I have several different folders which all contain one single .csv file. All of those .csv files have one single column containing the data of one condition of an experiment. I would like to merge those .csv files in such a way that the data of every file is added as a new column. At the moment, it Looks somehow like this: C1.csv 102 106 152 196 223 486 553 C2.csv 296 299 843 1033 1996 However, it would like to have one single .csv file, where all the separate files are copied into a new

问题 Let's say I got a table like this: data <- c(1,2,3,6,5,6,9,"LC","LC","HC","HC","LC","HC","ALL") attr(data,"dim") <- c(7,2) data [,1] [,2] [1,] "1" "LC" [2,] "2" "LC" [3,] "3" "HC" [4,] "6" "HC" [5,] "5" "LC" [6,] "6" "HC" [7,] "9" "ALL" Now I want to manipulate the data so it looks like this: [,"LC"] [,"HC"] [,"ALL"] [1,] "1" "3" "9" [2,] "2" "6" [3,] "5" "6" Is there a way to do this in R or is it just impossible and should I try another way of getting access to my data? 回答1: You can get

问题 I have a page that uses a mat-table with expandable content. I need to be able to have a click event that records the row number of the table that I am clicking on. Now, if I have a table without the expandable content I can successfully use the following in the html file: <tr mat-row *matRowDef="let row; columns: displayedColumns; let i = index" (click)="logIndex(i)"> and the following in the component file: logIndex(i) { console.log(i); } but this doesn't work with expandable content. Here

问题 I have the code below to hide/unhide entire rows depending on the corresponding cell value (hide if it's 0) and it works fine. This is a list of material and there is a 'finalize' button. At the end of the list you press the button and any item that has a quantity = 0 should hide this relevant row. It works fine. But the problem is that it's very slow. As you can see it's 400+ lines and I can literally see as the lines disappear. It's processing roughly 20 lines per second which makes it over

问题 I subclassed QTableView, QAbstractTableModel, and QItemDelegate. I am able to hover a single cell on mouse over: void SchedulerDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const { ... if(option.showDecorationSelected &&(option.state & QStyle::State_Selected)) { QColor color(255,255,130,100); QColor colorEnd(255,255,50,150); QLinearGradient gradient(option.rect.topLeft(),option.rect.bottomRight()); gradient.setColorAt(0,color); gradient

问题 This is my first time asking here so forgive me if something isn't appropriate, and sorry if my English isn't very good. Well, to make it short, currently I'm developing a Java desktop app with Swing and I have a problem using table. I have rows with each row have a button to delete the row. Everything is okay (i can delete rows with no problem) until i try to delete the last row. The last row can be deleted but apparently there is an exception, something like this: Exception in thread "AWT

问题 I have a question and I could not find the answer on the internet nor on this website. I am sure it is very easy though. Let's say I have a set of 20 numbers and I have them in a 5x4 matrix: numbers = np.arange(20).reshape(5,4) This yields the following matrix: [ 0, 1, 2, 3] [ 4, 5, 6, 7] [ 8, 9, 10, 11] [12, 13, 14, 15] [16, 17, 18, 19] Now I would like to have the minimum value of each row, in this case amounting to 0,4,8,12,16. However, I would like to add that for my problem the minimum
