Updating packages from one hard-drive to another, after upgrade of R

The CPU on my computer 'died' and I have had to purchase a new 
computer. I have just installed v 2.6.2. My previous computer had v 
2.5.1 and a large number of files in the library folder. These files 
have been copied to a partition on my new hard drive, along with the 
old R installation.

Can I just copy all the folders/files in the old library to the new 
v2.6.2 library or do the packages need to be downloaded again? There 
are quite a number of folders so it would be time-consuming to have 
to do a fresh download.

Any assistance is appreciated,

Bob

Bob,

You can copy the files from the packages to your new computer. Then run
update.packages(checkBuilt = TRUE).

That should do.

HTH,

Thierry

See ?.libPaths for info on setting the location of your libraries.
If you do want to copy them the copydir.bat utility in
 batchfiles.googlecode.com
can do that.

Well, that will download new copies of all the packages, something he was 
trying to avoid.  It is close to unavoidable, though, as installed 
packages are only expected to work correctly with 2.x.y for a single value 
of 'x'.  The repositories have different collections for the binary 
distributions for 2.5 and 2.6.  Here we don't know the OS or how the 
packages were installed

If downloading really has to be avoided I would suggest using 'old' 
directory as a separate library (if the is Windows, see the rw-FAQ) after 
removing the duplicates (the base and recommended packages) from the new 
library directory.  And be prepared to download updates if things go 
wrong.  The main issue is packages using S4 methods, e.g. Matrix -- if you 
have the latter, make sure you do reinstall it.
