Installing RPy in Windows - Versioning Error

[KristinAldous]

Any Hello,

Does anyone know what versions of RPy, R, and Python are compatible?

I'm hoping to access RPy for a small, but important, part of a project.  I have R 2.1.5.2, Python 2.7.2 in ArcGIS 10.1, and RPy (ver1).  I am trying to install RPy2 to give that a try, however could only find a source code version and have never compiled software.

Here's my error:

>>> import rpy
Runtime error 
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\Python27\ArcGIS10.1\lib\site-packages\rpy.py", line 136, in <module>
    """ % RVERSION)
RuntimeError: No module named _rpy2152

      RPy module can not be imported. Please check if your rpy
      installation supports R 2.15.2. 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 *

I've followed the instructions at http://rpy.sourceforge.net/rpy/README and have:
    o Python
    o R 
    o Numeric  (http://numpy.sf.net)
    o win32all, windows extensions from Mark Hammond
      (http://starship.python.net/crew/mhammond/win32/Downloads.html)
   o As well as RTools

And have set my path variable as instructed here:

Any suggestions are much appreciated!

Got it!

I ended up installing R 2.12.1 with RPy ver 1 in Python 2.7.  Not sure if it was the version or path names that were the issue.

Anyways, thanks for reading!
