Hi, Adelchi,
Depends on what you want help with...
The proximate cause would seem to be that the code ought to have
"is.null(A) || any(is.NA(A))", which I presume you could fairly easily
fix for yourself in the package sources or even locally in an R session.
Vector-valued logicals in flow control constructions have gone through an
elborate deprecation process before getting turned into errors.
If the problem is how to activate a dormant maintainer and fix the issue for
everyone, I don't really have a clue, but you might consider cantacting the
CRAN team.
Best,
Peter D.
