Could you post the code that you've tried so we can see if this is reconcilable
within python/rpy2 or if it is, indeed, an R problem?
cheers,
brandon

Subject: Re: [Rpy] export a package of R in python program
Hi
I have already done this because each package has different suffix which shows
the version of the package. I imported in the program both of them but since
the name of the function is the same in both and it needs different parameters
in each one, it makes a big mistake. I figured out that even I call the
function with the prefix of the package it only realized the last one.

There's no way of specifying versions in R's library() function, so I'm
assuming that if you successfully have both versions of the package installed
in R, they must have different names (I'm pretty sure installing a new version
of a package overwrites the previous version). If that's the case, using the
latest version of rpy2 (2.1.0-rc):
