Using R-2.3.1 You don't make the package directly in your library directory. Just make it somewhere like /home/tnayar/ and then in a terminal do R CMD INSTALL <packagename> which will install the package into your library directory. If your R directory isn't in your PATH, then you may have to do /home/tnayar/R-2.3.1/bin/R CMD INSTALL <packagename> I would also upgrade to a current R version. The one you are using is pretty old now.
