OK. I have made some tests this morning to figure this all out.
Indeed, the problem with ">" is that it catches every single message R

to STDOUT and not only object of your interest, so this is definitely not a
reliable solution. Solution suggests by Alex worked perfectly well.
I would suggest also to use the 'trailingOnly=TRUE' option within the
commandArgs() call in the R script. That allows you to only care about the
args given after the '--args' option. You can then forget how many previous
options you have in your command line (--vanilla, --slave, -f or others...).
First parameter useful to your R script would then be
commandArgs(trailingOnly=T)[1] and so on.
That is a very handy tip, commandArgs(trailingOnly=T), thanks!
There is just another little point that I would like to clarify. At
the
beginning my tests didn't work at all and I realize that I have to give the
full path to the R script (in the command tag) to make it work.
What happens if you do <command> rather than <command
interpreter="bash">?

P.S. Cross posted to Galaxy-dev, could we continue this there?
