[R] Updating R

[CG Pettersson]

Hi!
The installing and updating functions for packages in R (install.package() , update.package()) really impresses me in behavior.
For the moment I run R 1.5.1 and got warning messages after installing the "multcomp" package, as it is built under R 1.6.1.
Is there any similar smooth ways of updating the R-version as there is for packages? I´ve looked in all places I can think of but can´t find any hints.

Thanks
