Hi

is there an easy way of re-installing all packages in my user library?
I am not referring to checkBuilt=TRUE, but re-install all packages,
irrespective of the version.

Reasoning: I installed Simons patched R for Mac to use the new C
compiler, and I would like to re-install all packages to make sure
that they are not compiled with the old compiler, as this can cause
problems.

I manually removed all Rcpp* packages and re-installed them, but this
is not a real solution.

I also have seen e.g.

http://www.r-bloggers.com/automated-re-install-of-packages-for-r-3-0/

But I am wondering if there is an easier approach?

Thanks,

Rainer
