You should not install your packages to the library path of R itself but
to something like `$HOME/lib/R' and tell R about it (via the R_LIBS
environment variable, see section 4 of R Installation and Administration).

Note that in contrast recommended packages may be installed in R's install
directory and that is what's happens by default.

Best,

Torsten
