I manually downloaded the rpart package and installed it using dpkg, without removing the old rpart package first, and now everything works. During the installation, dpkg said:
Unpacking r-cran-rpart (4.1-13-1cran1xenial0) over (4.1-13-1cran1xenial0) So again, it seemed that the new version had been installed, but it really wasn’t. I had no idea that something like this could happen. Huh. Anyway, thank you very much for your help!

Everything works except loading the rpart package in R: Not quite sure if this has been resolved. I can confirm that the Xenial rpart packages on the RRutter3.5 PPA is indeed built against R 3.5. The rpart packages on CRAN is the same as on the PPA, so I believe this is an isolated incident. Sometime the dist-upgrade leaves a few breadcrumbs that need to be cleaned up. If all else fails, remove the installed rpart package, download the correct binary from CRAN or the PPA, and install with dpkg.
