R help - Jan 2009 - Calling R functions from Python

All-



   Thanks in advance for your help.



   I'm trying to call R function using Python in a windows environment and
have
   downloaded the Rpy library however it doesn't appear to work with R
2.7.2.
   Does anyone know if a new version of Rpy exists for windows that will work
   with R and where it can be downloaded from?





   Here's an example of the error I'm getting:



   Traceback (most recent call last):
     File "C:\Documents and Settings\rkirkish\Desktop\test.py", line
1, in
   <module>
       from rpy import r
     File "C:\Python25\Lib\site-packages\rpy.py", line 134, in
<module>
       """ % RVERSION)
   RuntimeError: No module named _rpy2072

         RPy module can not be imported. Please check if your rpy
         installation supports R 2.7.2. If you have multiple R versions
         installed, you may need to set RHOME before importing rpy. For
         example:
   
         >>> from rpy_options import set_options
         >>> set_options(RHOME='c:/progra~1/r/rw2011/')
         >>> from rpy import *

Hello Ryan,

I have good and bad news for you.

The good one is that there is a new rpy in active development. The bad one
is that you should compile it yourself.

You can get it here

http://rpy.sourceforge.net/rpy2.html

I use the regular distro of rpy under Linux x86_64. It works. I hope you get
your windows to work as well. To start with, I suggest that you upgrade to R
2.8.0. By now R 2.8.1 is the official version for Fedora (linux) users. So,
we can consider 2.7 rather old.

Best,
