That is odd. Possibly an rpy problem - hopefully someone else can
comment on this bit.
The work around is to create the array yourself explicitly. This works
for me:
>>> from rpy import *
>>> import Numeric
>>> c = Numeric.array([[386, 113], [385, 117], [383, 117]])
>>> c
array([[386, 113],
[385, 117],
[383, 117]])
>>> r.chisq_test(c)["p.value"]
0.9535284154083411
But it sounds like you tried something like this already...

In python, what does this print?
>>> array(c)
