Hi, my problem belongs to the basic ones. I want to get cumulated sum over the matrix columns by one command (if such exists). Ordinary R's cumsum(x) when x is: [,1] [,2] [1,] 1 5 [2,] 2 6 [3,] 3 7 [4,] 4 8
yields: 1 3 6 10 15 21 28 36 I want: [,1] [,2] [1,] 1 5 [2,] 3 11 [3,] 6 18 [4,] 10 26 Is there any command to do so?? best, robert -- View this message in context: http://www.nabble.com/cumsum-tf4742648.html#a13562053 Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
