I have a number of machines in a home LAN that share /usr/local where
I have all but a few R-packages that are automatically installed by
the OS package-mangagement system (by installing the meta package
r-recommended).

I have the following snippet in my .Rprofile

lib.loc = "/usr/local/lib/R/site-library/"

so whenever a package is installed, all machines have access to it.

This will of course not work if the machines are running different
OS:es, so that is not irrelevant.
