[R-SIG-Mac] R Versioning and Packages

[Roy Mendelssohn - NOAA Federal]

Hi All:

Since R 3.2 has been released and the Mac version should be available shortly, I always forget how the R versioning system and updates relate to installed packages. Some updates work with what you have installed, some do not.  I know if the update was to R version 4.x I would likely have to re-install packages.  Will this require reinstallation, and in general at what level of update is this the case.

Thanks,

-Roy M.
