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.
