[Numpy-discussion] working with matrix....

I must analyse many data (about 2000 historical series of two variables). This data are organized in matrix. I must calculate some simple statistical analysis, and I must write a script for to automate the processing. I've a simple question: What's the better method or working (I'm a beginner of python and R): - Numpy - Bash shell + R - Rpy + R - Other possibilities?? Thanks in advance, Alfredo
