Thanks. I do biology with limited amount of data and my needs are very basic. Here is a software I wrote to do sleep analysis in Drosophila: http://www.pysolo.net

So far I could satisfy most of my statistics needs with the function in numpy and scipy but occasionally I need to do something slightly more fancy and R I guess is the way to go.

Possibly. R is really great at doing "fancy" statistical analyses. It's very lousy at doing things like text manipulation. When I have a project that needs some text manipulation on the front end, I frequently use other tools (Python, vi, sed, ...) on the front end to beat text data into a nicer form for R. I couldn't say without knowing more about your project.
