[R] upgrading R

[Mulholland, Tom]

This has been discussed with previous upgrades. One such discussion was
"How to update installed packages to a new version of R?".
http://finzi.psych.upenn.edu/R/Rhelp02/archive/8316.html  There are a
variety of methods to choose from. You may also learn about updating
packages directly from the net which can take care of the issues of
having to reinstall packages.

I am not sure if this is a proper way, but here is what I did recently
installing consecutive alpha and beta releases of 1.8.0 on a Win2000
machine:
(1) I uninstalled previous version using the uninstall provided with R.
This leaves all the additional packages in the library folder
(2) I reinstalled the new version into the same folder structure.

The problem might be that some 1.7.1 packages might be different from
1.8.0, so it might be safer to reinstall them from CRAN.

Hi,

I have installed a lot of extra packages for R 1.7.1. If I install R
1.8.0, will I have to reinstall all those packages? Is there a way that
I can upgrading R without losing old packages?

Thank you.
