Hi, I have a vector that looks like this: RowSel <-c(0,1,0,1,2,3,0,5,5)
Now I want to select rows from a specific dataframe DF based on that vector like this: SubDF <- DF[RowSel,] So this works fine, but I was wondering how I could add blank rows add the locations in the vector where there is a zero: So the final dataframe should look like this: SubDF [1] blank row [2] row 1 [3] blank row [4] row 1 [5] row 2 [6] row 3 [7] blank row [8] row 5 [9] row 5 Do I have to use a loop for this or does there exist a straight forward function option. Thx, Bert ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
