OK, understand this is a complex operation, but still unfortunate. The
mixing of c2d4u packages with r-base 3.5 will inevitably happen when
people upgrade their systems to R 3.5.

If there would be a way to start adding the appropriate r-api-nn tag
in c2d4u based on which version of R it was built with, that would
probably be an enormous improvement. Not sure if this is something
that can easily be automated.

Thanks for your efforts on this!
