R help - May 2006 - everytime I download a new version of R, need I reinstall all packages?

Can the packages that I've installed in R 2.2.1 be automatically imported to
R 2.3.0?

Otherwise it is a hassle everytime I update a new version of R...

I think you did not answer my question... I now upgraded my main R program
from 2.2.1 to 2.3.0 and I removed the 2.2.1 installation, but all the
libraries that I've installed myself previously in 2.2.1 are now gone... I
have to reinstall them one by one... in 2.3.0

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.)

Wait until after you use update.packages() to remove your previous
installation. You can keep multiple versions of R simultaneously, so this is
no problem. That is:

1) Install new R version
2) Run update.packages() on old library version
3) Copy updated old library to new library location (or point new library
location to old)
4) Remove old R version (and its libraries if you copied them)

There are probably better ways to do this, which this message may stimulate.
