[R] everytime I download a new version of R, need I reinstall all packages?

[Gabor Csardi]

Well, 

if you removed your installed packages together with R then of course you
need to reinstall them.... consider installing the packages in a separate
directory, not in the R tree. (I install packages into ~/.R/library on my
Linux box for example.) This way at the next R update you don't need to
reinstall them. (If they are compatible with the new R version.)
