I am unsuccessful at using rpy through the sage notebook. A Traceback
is appended. I am assuming this is the sage interface to R (through
'from rpy import r'). I have spent the last few hours learning the
rudiments of sage, python, R, and rpy, in that order. I am using the
Ubuntu Hardy with the Linux binary distribution:
sage-3.0-ubuntu64-opteron-x86_64-Linux.tar.gz
I have separately installed R-2.6.2 and the latest debian package for
rpy (as there is an Ubuntu bug that generates the same Traceback on
importing rpy). I am wondering how to fix this problem as it looks
like my installation of sage uses it's own local version of
everything, but I'm not sure. I've tried different set_options()
unsuccessfully.
Before hacking into the sage distribution and given I have no idea
what I'm doing, I was wondering if this is indeed the interface to R
and if there is a quick fix for this problem. I have read through some
of the trac tickets and postings on your forums but I don't know
enough at this point to solve this myself.

RPy module can not be imported. Please check if your rpy
installation supports R 2.6.2. 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 *
