Forget about anything your wrote above and delete what you entered.
A clean installation should provide you with a personal library for 
packages anyway. If that is not the case, you can also set an 
environment variable R_LIBS_USER whjere you can point to any directory 
(=library) where you'd like to install packages.

See ?Startup and ?.libPaths and of course the R Installation and 
Administration manual for more help.

Best,
