I've been working on this transition in Ubuntu and here are some of my notes:
rgtk2 and rggobi now FTBFS on s390x, they also fail in a Buster chroot on zelenka.debian.org so I don't believe it is a regression in R, but the binaries will need to be removed. r-bioc-iranges, r-bioc-variantannotation and r-cran-dplyr need to be updated to work with R 3.4.2. You can see from the autopkgtest results [1][2] that started failing on 2017-09-24. Unfortunately, r-cran-dplyr 0.5.0-1 has always failed its autopkgtests, so the results aren't useful.
