You need to uninstall packages directly (they are kept independently of R,
which is actually quite helpful when updating so you don't have to get them
all anew): this can be done within R by combining remove.packages() and
installed.packages(). To delete the workspace you need to manually remove
the .Rdata folder in your start-up working directory.

Hope this helps
