[R-pkg-devel] Bioconductor reverse dependency checks for a CRAN package

[Ivan Krylov]

Dear Dirk,

Thank you very much for your help here and over on GitHub!

I have finally managed to get the reverse dependency checks working. It
took some additional disk space and a few more system dependencies. If
not for r2u, I would have been stuck for much longer. I really
appreciate the work that went into packaging all these R packages.

This approach seems to be working for me, too. I had initially hoped to
set something up using CI infrastructure, but there's too many
dependencies to install in a prepare step and it's too much work to
make a container image with all dependencies anew every time I want to
run a reverse dependency check. Easier to just let it run overnight on
a spare computer.

Maintaining a top-5 CRAN package by in-degree rank
[10.32614/RJ-2023-060] is indeed a very serious responsibility.

I'll check out `prrd` next, thanks. tools::check_packages_in_dir is
nice, but it could be faster if I could disable mc.preschedule.
