Set the lib argument to install.packages to a directory in which you
do have write permissions.  From ?install.packages
...
     install.packages(pkgs, lib, CRAN = getOption("CRAN"),
                      contriburl = contrib.url(CRAN),
                      method, available = NULL, destdir = NULL,
                      installWithVers = FALSE)
...

lib,instlib: character string giving the library directory where to
          install the packages.
