Thanks, Michael. I did some simple tests, upgrading existing r-base
installations to R 3.5. on Xenial and Bionic, and initially apt did
the correct thing of removing the incompatible r-cran-xyz packages.

However then I tried installing the (knowingly incompatible)
r-cran-rcpp from c2d4u and apt didn't stop me. Do the r-cran-xyz
packages from c2d4u not have the same r-api-nn dependency
restrictions?
