Cathy…
Regarding changes from last year, I wouldn’t worry too much about that. The
CRAN checking system is always moving toward greater stringency as the
ecosystem evolves. Requirements and messages change steadily.
I have “chased my tail” along the lines of your original description before as
well. There are ways to import the entire namespace of a package which allows
one to get a working package but there the current standard is to import only
the particular functions you need, not the entire namespace. And there are
differences between writing
assertr::col_concat()
and
col_concat()
in your functions too, depending upon what you import (I may be remembering a
detail incorrectly here).
