An email from you with no explanation points (!). Moreover, your email about R also had no explanation points: "Just a few words on that one... I have had to stand statistics for one year at the university, and I really ate R from morning till evening... Even though I have forgotten almost all of it, there are still two things for which R is vastly superior to python : matrices and plots. This does not make it a better language than python, that's perfectly True, but to anyone who would like to rewrite in Sage some code written in R, this would mean a HUGE amount of work. The manipulation of matrices in R is just amazing. If you want to strip all the negative values contained in a matrix M, you but have to write M * (M > 0). How easier can it et ? There is a thousand tricks like that available in R that I noticed nowhere else. And the same goes for plottings using R. I mean that on these two points, the R language is much more expressive than any other I know.
