Hello All,<br><br>    When running a grouping on a data set via the Join, Subtract, Grouping menu, I receive this error.  <br>An error occurred running this job: <i>Traceback (most recent call last):<br>  File &quot;/opt/Bio/galaxy_dist/tools/stats/grouping.py&quot;, line 7, in ?<br>
    from rpy import *<br>ImportError: No module named rpy<br><br></i>I&#39;m having the hardest time figuring out which R version with what version of Rpy to use.  So far I&#39;ve tried rpy-1.0.3, rpy2-2.0.6, with Rpackages 2.7.2 and 2.9.1.  I&#39;ve gotten both rpackages to compiled with the --enable-R-shlib option and I have put it in my $PATH.  However, when trying to install either of they rpy packages, they complain about missing header file RGraphics.h, Rdevices.h, and more.   Does anyone have a known good configuration to get this module working with galaxy?  Which R package with which rpy version should I be using?<br>
<br>Thanks,<br>Hans Vasquez-Gross<br><br>
