On my Ubuntu (20.04.4), my R installation recently updated to 4.2.0. This led to me not being able to load my packages, but having to reinstall them. (More unfortunate was that I was traveling to a conference just after this happened, and I had limited access to the internet, meaning that I could not alter my figures anymore.)
I have now unchecked https://cloud.r-project.org/bin/linux/ubuntu in Ubuntu's Software & Update. I was wondering if anyone had more tips on guaranteeing that R is only updated when I want it to? An extra reason for doing this is that having software updated during an analysis could lead to irreproducible behaviour.
Also, even though I have by this time installed all my packages again; is there any quick way to do the transfer? Reinstalling from scratch seems inefficient.
R packages need to be compiled for an specific R version (at least for a specific major version) so sadly reinstalling after a major R upgrade is mandatory but you can save considerable time if you use precompiled binaries from the RStudio Public Package Manager
