Package: r-core-case
Version: 2.13.1-1
Severity: wishlist

Hello,

The Debian packages for R add a "/usr/local/lib/R/site-library"
directory into which the local sysadmin can install packages, which is
really useful. However, compiled R packages are not always compatible
between versions of R (e.g. going from 2.9 to 2.13), and not having a R
version number in that directory path makes migration to a new R version
without breaking anything a bit complicated, at least for sites which
have multiple machines accessing a common /usr/local via NFS, etc.

Would it be possible to also add a "/usr/local/lib/R/%v/site-library" at
the front of R_LIBS_SITE? That way local packages could be installed in
that directory and there wouldn't be any problems when changing versions
or R, or running multiple versions on different computers, etc. The "%v"
is used in other places already (packages installed in a user's home
directory, for one), and given that the R ABI can change between
version, I was a bit surprised that said "%v" wasn't used for the
/usr/local path too. (Actually, I initially thought that R didn't change
its ABI for modules.)

Thanks,

  Christian
