R help - Dec 2008 - Make installed packages available to new R version

After installing a new version of R, how do I make the packages that I 
have already installed and use on the old version available to the new 
version?

Thank you,

Roy Robertson

Have a look at this

it is safer to have all you packages reinstalled once you have updated R.

HTH.

Here is my solution. It has worked over many releases of R,
though it will probably require one initial re-installation of
packages.

Set environment variable R_LIBS to some permanent directory
before installing a version of R. (That is, NOT a directory
under the tree of your current R version.) When you subsequently
install packages, they will go into that location and won't need
re-installation with each new version of R. 

It's still necessary to run update.packages() periodically --
such as after installing a new R version -- to keep the
installed packages current.

You have not told us your OS (despite the posting guide).

For Windows this is covered in the rw-FAQ.  Similar advice would apply on 
a Unix-alike.

For Mac OS X, see the recent archives of the R-sig-mac list. E.g. the 
strangely titled threads (look in a threaded view) around

(probably using the Package Installer).
