That is where R *downloads* the package files (for temporary storage),
but it is not where they are installed.  By default, they are
installed in the (first possible, I think) path of .libPaths().

You can see the installation path by, for instance,

packageDescription("base");

and

packageDescription("nnet");

with the 'nnet' package.  Try to install another package and see if
that works.
