I am using rpy2-2.0.3.
I am using Python and R in the shared library and don't know if updating
them will cause problems to other people's scripts. But I will try to get
updated Python and R in my local directory and retry.
BTW, if i upgrade R, would rpy2 can find R? Or should i reinstall rpy2?
Thanks for looking into this!
