Have your read an Introduction to R? If not, do so before posting further. There are also many "R for SAS users" tutorials on the web I'm sure. Google or check CRAN. In particular, you need to understand how indexing works. See ?"[" and ?subset
You will certainly have to define what you mean by "just over". Once you do so, ?cumsum will do what you want (once you learn about indexing in R). -- Bert On Tue, Sep 18, 2012 at 7:41 AM, ramoss <ramine.mossad...@finra.org> wrote: > Hello, > > I am a newbie to R coming from SAS background.
