Statistical Programming With R
An anonymous reader writes "This series introduces you to R, a rich statistical environment, released as free software. It includes a programming language, an interactive shell, and extensive graphing capability. What's more, R comes with a spectacular collection of functions for mathematical and statistical manipulations -- with still more capabilities available in optional packages."
For people who have never taken real stat classes in college (or never learned it on their own) R will seem like a useless language. Most other languages can handle basic statistics computations.
Statistics is a whole lot more than means and averages. When I took my first real stat class, everything I knew about statistics was literally covered on the first half of the first page. I was totally blown away by what you could do with statistics.
R is for hardcore stat folk who know a bit about programming, not programmers who need to do a little basic computation.
