Dear BioC, I have to set up a facility that will run R-Bioconductor for different users on a linux platform. They actually complain about the installation of metadata, as they dont have permissions to install them. Is there a way to give them partial permission to install these packages and further R packages without give them root controls? thanks to all Claudio

Hi Claudio, it is a really bad idea to install R with root permissions. While I am not aware that it has ever happened, it is only a matter of time until some idiot hides a virus or trojan in a contributed R package. Can you create a group "biocusers" of which these people are members, and then give that group r/w permission to the "library" subdirectory of the directory where R sits. This might lead to interferences (since different people might want to use different versions of packages), then the best solution is for each user to have their library (i.e. the directory with the packages) in their home directory, and to set the R_LIBS environment variable e.g. in $HOME/.Renviron.
