No its not. I am doing all these experiments for my own learning purpose. I am Oracle SQL & PLSQL programmer and I can do these things with Oracle analytical functions.
However at present I am keen to learn R, with no other interest right now.

This sounds to me very much like a homework problem. We don't do people's homework for them on this list. cheers, Rolf Turner -- Technical Editor ANZJS Department of Statistics University of Auckland Phone: +64-9-373-7599 ext. 88276 ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
