[R] Troubles with stemming (tm + Snowball packages) under MacOS

[Julien Velcin]

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 ---
