That would appear to be an error in the locally installed R.
What the package does has been discussed before. Per the Linux Filesystem
Standard (or Filesystem Hierarchy or whatever it is called), Linux distro
such as Debian and Ubuntu use _both_ /usr/lib _and_ /usr/share so the
directories are split. Use the `R.home()` function to find them:
$ Rscript -e 'sapply(c("bin", "doc", "etc"), R.home)'
bin doc etc
"/usr/lib/R/bin" "/usr/share/R/doc" "/usr/lib/R/etc"
$
That is from the packaged R via r-base-core.
The behaviour can easily be validated by invoking, say, a Docker container
based on these same (Debian) packages. One of the containers I look after in
the Rocker Project has also been aliased to just 'r-base' for years by Docker
itself so just prefix the above by 'docker run --rm -ti r-base' to run in a
clean container:
$ docker run --rm -ti r-base Rscript -e 'sapply(c("bin", "doc", "etc"), R.home)'
bin doc etc
"/usr/lib/R/bin" "/usr/share/R/doc" "/usr/lib/R/etc"
$
Being able to run Docker for such tests is a good superpower and on most
systems these days only one package installation away.
For a locally built one (my r-devel build here) it works the same but points
of course to a different directory:
$ RDscript -e 'sapply(c("bin", "doc", "etc"), R.home)'
bin doc
"/usr/local/lib/R-devel/lib/R/bin" "/usr/local/lib/R-devel/lib/R/doc"
etc
"/usr/local/lib/R-devel/lib/R/etc"
$
As suggested, question for 'R on Debian, Ubuntu, ...' should probably go to
r-sig-debian which is now CCed. As usual, you must be subscribed to post or
else you will get mistaken for a spammer and ignored.
