If you can get this to work, it would be nice to include in the Galaxy repository. J.___ Please keep all replies on the list by using "reply all" in your mail client.

Re: [galaxy-dev] How to manage stderr output from R?
Hi Jeremy,
Thanks for your quick response.
I'll try switching from using 'tools/plotting/r_wrapper.sh' from
Galaxy distribution, to my own wrapper using python, so I can use your
advice.
I still wonder if this is the best way to run R's scripts? I would
have thought there would be a simpler option. I wonder if
"r_wrapper.sh" could be improved to absorb stderr messages, I would
guess Bash has these capabilities.
Thanks,
Carlos

Re: [galaxy-dev] How to manage stderr output from R?
Carlos,
You'll want to have your wrapper collect output to stderr and report only if
the tool fails. See the Cufflinks/compare/diff wrappers for examples of how
this can be done.
Good luck,
J.
