Hi,

when updating R I continuously face the problem that I have to reinstall packages or copy them into the new R library path.

Is there a smart way of configuring R (.Rprofile) so the packages installed under older R versions (different lib paths) are included/found by newer R versions (e.g. R site archive).
What problems due to version conflicts/out-of-date packages can arise?


See the manual R Installation and Administration on how to use library trees and how to update all packages for the recent version of R. If you do not recompile / update for a new major release of R, some packages (and packages that depend on them) may not work anymore (due to API changes, changes in S4 classes and so on).

I am working with R on a Linux server.

Thanks in advance,
