Well, R already allows you to source packages from different
directories. E.g. for Debian, we have long used
edd at basebud:~> grep -B2 R_LIBS /etc/R/Renviron
# edd Apr 2003 Allow local install in /usr/local, also add a directory for
# Debian packaged CRAN packages, and finally the default dir
/usr/local/lib/R/site-library 'user' stuff
/usr/lib/R/site-library debs but not r-recommended
/usr/lib/R/library debs from r-recommended
Now, if I wanted to, I guess I could modify our already effectively automated
scripts that build the few r-cran-* Debian packages to
a) detect if they are 'arch' or 'noarch', and
b) in the case of 'noarch' install into a fourth location
/usr/share/R/site-library 'noarch' debs
provided that R_LIBS has also been updated to look there.
Conceptually at least, this should work. Ultimately, the FHS has a valid
point and R Core may decide to eventually support this automagically -- just
as R did move towards some support of /usr/share/R after some prodding
following an initial bug report by a Debian user.
That said, I think the OP from the bugzilla report you referenec may not be
aware just much a 'one file tree below $R_HOME' view R itself (still) has,
but that is a different story.
Hoep this helps, Dirk
Hell, there are no rules here - we're trying to accomplish something.
