I'm wondering if there is a way to get a list of reverse dependencies on
CRAN that includes archived packages.

I am asking because "ashr", an R package I maintain, was recently removed
from CRAN, and now it is back after I fixed the critical problem.

However,

some of the downstream packages that were affected by this removal are no
longer listed as a reverse dependency.

I think that the easiest way is to use Microsoft's CRAN time machine
[1]. Simply set the session's repo to the day before the archiving
date, and then you can get the complete list using regular procedures.
