Hi Sarah
you need to install the rpy module:
http://rpy.sourceforge.net/rpy.html
As a warning: we have been struggling to get rpy to work with newer
versions of R. In or experience in only works with R version 2.9 and
older. Thanks to a recent effort of our sysadmin, we can now use it with
2.15 - which is good, but not great, as our default version of R is now 3.0
Although we haven't started to us it, I recommend using rpy2:
http://rpy.sourceforge.net/rpy2.html
Most tools have been refactored by John Chilton
see: http://dev.list.galaxyproject.org/rpy2-Core-Tools-td4659832.html

Hello,
Some Galaxy tools failed to import rpy module and displays the following
message:
Traceback (most recent call last):
File
"/usr/local/bioinfo/src/galaxy/galaxy-dist/tools/plotting/histogram.py",
line 5, in <module>
from rpy import *
ImportError: No module named rpy
For instance, the tool "Regrouping" (tools/stats/grouping.py) have been
refactored in 2011 by Kanwei Li to use numpy instead of rpy. And this
tool runs on my local instance of Galaxy.
But I would like to be able use rpy module instead of refactor the
others tools.
Could you, please, help me to understand why the eggs ' import does not
allow the use of rpy module? How to debug these tools?
Thnaks in advance,
Sarah
