Thank you so much Peter, finally it works.

Hi,
Are you by any chance working on a 64-bit system? If so, have you
tried using numpy and the patch I submitted recently?

That does look like the same issue - I personally haven't been affected
yet. Please add a note to the bug on sourceforge, with the versi

Hello again Peter.
I noticed that I didn't had Numeric installed, now that part is solved, but
it didn't solve the problem.
I still get a list of lists not an array:
>>> c1=[386,385,383]
>>> c2=[113,117,117]
>>> c=r.cbind(c1,c2)
>>> c
[[386, 113], [385, 117], [383, 117]]
>>> r.chisq_test(c)
rpy.

You are right -
Hi Peter,
Thanks for answering. Unfortunately your suggestion doesn't work with the
version we are using (Python 2.4.3, R 2.4.1, Rpy 1.0 RC2). It seems that
chisq function is waiting for a matrix as a double and not as a list. How
can we solve this?
Thanks in advance.

Hi,
We'r trying to do a chisq test from Python using Rpy but the p-value result
is different depending if we do it directly in R or Python.
So the mistake must be in the way that data is defined.
Can someone help us in this matter?
Thanks in advance.
