Ok but unfortunately JGR doesn't work when run as root! I think this
is because the packages needed (e.g., rWeka) are installed locally
(for the user). The installation "at system level (in R framework)"
fails:
"Currently it is not possible to install binary packages from a remote
repository as root.
Please use the CRAN binary of R to allow admin users to install system-
wide packages without becoming root. Alternatively you can either use
command-line version of R as root or install the packages from local
files."
If I follow these advices (launch R as a root and try to install the
package manually):
> install.packages('RWeka')
--- Please select a CRAN mirror for use in this session ---

Running as root doesn't mean you can bypass the JGR trick. I think
you're experiencing two different problems here, so you still need to
apply the workaround for the first one.
Cheers
