Hi Firas, I had similar problems working in linux. If it's also your case, I solved changing administrative privileges to paths were all packages are installed: sudo chmod 777 -R /usr/lib/R sudo chmod 777 -R /usr/local/lib/R/site-library Maybe this is not the conventional way, but allows me to update all libraries without creating a new personal folder each time R is updated to a new version.

Does install.packages() with a CRAN package selection work for you? If it does not, you should study the R installation and administration guide available at R project manuals, and pose residual questions at r-help. Defining folders where packages can be installed can be accomplished with .libPaths() in the session. Check the value of this, and add a writeable folder and try again once you have done so. If you can make no progress with this advice, send the result of sessionInfo() and the attempted values of .libPaths and perhaps more concrete advice can be given. The details will depend on the specific version of windows you are using along with aspects of the security setup, which may not be readily reproducible outside your site. But in general you should be able to install libraries in personally writeable folders, without administrative privileges, you just have to set the parameters appropriately. These are laid out in some detail in the installation and administration manual.
