[R] unable to use functions require DLL from package "base"

[Prof Brian Ripley]

I suspect you have more than one version of R installed and are mixing 
them up.  Those symbols have been in package stats for quite a while.

Try starting R with --vanilla, and if that works, clean out your startup 
files (see ?Startup).  If not, remove all your R installations and 
reinstall R 2.7.0 (or R-patched).
