[R] What to do when problems() returns nothing

None of this is for R's *standard* packages. The posting guide, linked
below, says:

"For questions about functions in standard packages distributed with R (see
the FAQ Add-on packages in R
<https://cran.r-project.org/doc/FAQ/R-FAQ.html#Add-on-packages-in-R>), ask
questions on R-help.
If the question relates to a *contributed package* , e.g., one downloaded
from CRAN, try contacting the package maintainer first. You can also use
find("functionname") and packageDescription("packagename") to find this
information. *Only* send such questions to R-help or R-devel if you get no
reply or need further assistance. This applies to both requests for help
and to bug reports."

More to the point, the tidyverse galaxy tries to largely replace R's
standard functionality and has its own help forum. So I think you should
post there, rather than here, for questions about it:
