Migrate packages between different R minor versions
Once a year a new R minor version is released which requires the reinstallation of packages as the library path changes.
While there is no dedicated subcommand in rcli available (yet) to help with this task, here's a code snippet to do this "manually". Note that this snippets references library paths from a macOS arm64 machine. If you use a different one, you need to adjust the library paths accordingly!
Also the following assumes that you have already installed the new R version and use it as your active one.
rcli install rel # assuming 'rel' is R 4.2.0
lib_loc <- "~/Library/R/arm64/4.1/library/"
to_install <- unname(installed.packages(lib.loc = lib_loc)[, "Package"])
​
install.packages(to_install)
Note: This will only successfully reinstall packages available on CRAN. GitHub-only packages and local packages will fail.
