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?
