Too bad. (I seem to recall seing somehthing about numpy
conversion on the Web pages of RPy, though; perhaps, if one can stand
a bit of copying, the two can be used together after all?)

I think I'd want most of the standard, parametrized probability
distributions (as well as automatic estimation from data, perhaps) and
a handful of common statistical tests (t-test, z-test, Fishcher,
chi-squared, what-have-you). Perhaps some support for factorial
experiments (not sure if R has anything specific there, though).
And another thing: R seems to have vary fancy (although difficult to
use) plotting capabilities... Until SciPy catches up (it hasn't yet,
has it? ;) that might be a reason for using R(Py) as well, I guess.
