Hi all, I have a frequency data that looks like this. 3 2 1 5 What I want to get is the "decreasing" cumulative of this data yielding 11 8 6 5 0 Is there any? I am aware of cumsum(), which will yield 3 5 6 11. But it is not what I want. - G.V. ______________________________________________ [email protected] 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. ______________________________________________ [email protected] 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.
