Supporting R packages

Hi all,

I am one of the s390 porters of Debian and is working at IBM.
We here at IBM would love to see the r-cran-* packages work
on our platform. But given the current circumstances, working
on all of the failing bugs seems like something that is way beyond
my scope. I would love to fix at least the most crucial ones (or the
ones with the maximum dependency).
R being widely used in academia, is something we would love to see
on our platform.

Thanks,
Pranav
