Just got my echo back and it sounded a bit flip. Not my intention at
all. Apologies if you took it that way. Looks it would be simple to
build a small test problem in R. Once that is done, check out the RPy
tutorials on the web site. Should be able to code your R test problem in
RPy by line-by-line translation of the R code to RPy.

Re: [Rpy] Fisher's exact test
This might be a good start.

Yes, for sure I'll learn how to use R. I just needed a simple way to
calculate the Fisher's exact test from python. After a search I found rpy
and apophenia but the latter did not work correctly on my machine (I had
problems with SWIG installation).
