问题 I would like to find rows in which defined number appear (for example 2) for first time? For example: group <- c("a", "a", "a", "a", "a", "b", "b", "b", "b", "b") value <- c(1, 1, 2, 2, 1, 1, 2, 1, 2, 3) GOAL <- c("FALSE", "FALSE", "TRUE", "FALSE", "FALSE", "FALSE", "TRUE", "FALSE", "FALSE", "FALSE") data <- data.frame(group, value, GOAL) data In the column "GOAL" would be the result. Thank you for your help in advance. 回答1: This way assumes each group has at least one 2. Although your sample

问题 I'm trying to write a list to rows with a specific number of columns. For example, take the list: data = [1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0] I would like to write this out with a format such that it looks like: 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, I've tried the following code; however, can only get it to print the first line: strformat = ['{'+str(i)+':>5.1f},' for i in range(0,3)] strformat = ''.join(strformat).lstrip().rstrip() + '\n' print strformat.format(*[x

问题 I want to add rows to an already initialized JTable.

问题 I have a 10x10 Grid . And in each space I have added a label to which I added a mousedoubleclick event handler. So when I double click the label it's supposed to show the Row and Column number, but I only get 0 for both properties. This is the code... (and yes I have set Grid.SetRow and Grid.SetColumn for each label) private void grid_Checked(object sender, MouseButtonEventArgs e) { MessageBox.Show(Grid.GetRow(e.Source as UIElement).ToString()); } 回答1: Are you sure that everything is hooked

问题 I have an excel sheet where I'm trying to use conditional formatting but it doesn't seem to work as I would like it to. It seems as though any formula won't work as I don't want the cell to match TBC, but contain it. In short, I am looking for this: If D2 Contains "TBC" then highlight the whole row I've tried around 10 suggestions through Google and also Stack Overflow but it seems as thou Note: Each cell will have different values, i.e. D2 has "1 screenshot TBC" and D3 has "5 screenshots TBC

问题 I've a full width page with sidebar and content areas. I need sidebar with fixed width value and the content areas width is rest of the page. As you can see on bootply example the second row goes under my sidebar which should not. If I change .row:before, .row:after{display: table;} to table-cell, this problem looks solved however this is not a proper solution because it causes some other problems. http://bootply.com/89133 回答1: Wrap the main content in it's own section (or div or content,

问题 I need to reorder a data frame similar to the one below. I need London to appear first in any different Var, but it is quite critical to keep the var order as it is ("pop, gdp,lifespec...) as I am doing matrix algebra afterwards. City Var value Chicago pop 0.08 London pop 0.24 Paris pop 0.75 Chicago gdp 0.55 London gdp 0.49 Paris gdp 0.23 Chicago lifespec 0.45 London lifespec 0.39 Paris lifespec 0.28 Chicago percjobs 0.12 London percjobs 0.13 Paris percjobs 0.01 So my desired output would be

问题 I have found similar questions to mine, but none of them explains how to do that for each column of a dataframe. I have a dataframe like this: x1 = seq(12, 200, length=20) x2 = seq(50, 120, length=20) x3 = seq(40, 250, length=20) x4 = seq(100,130, length=20) x5 = seq(10, 300, length=20) df = data.frame(V1=x1, V2=x2, V3=x3, V4=x4, V5=x5) Now I want to get the number of values that are greater than 120 for each column. I have tried: nrow(df[,1] >120) That didnt work, it says 0, but its not true

问题 I would like to know how to get row count for jqGrid. I'm using rowNum: -1 so it displays all the rows. I tried using: parseInt($("#grid").getGridParam("records"), 10) But it always returns 0 . Thanks for the help. 回答1: Try: $("#grid").getGridParam("reccount") from the jqGrid documentation: reccount ( integer ): Readonly property. Returns the exact number of rows in the grid Note also that, as Mike commented, you need to use the getGridParam method with the records option to retrieve a count
