[R-pkg-devel] Checkpoint package failing CRAN checks

[Hong Ooi]

Hi all,

I'm the new (as of 6 months ago) maintainer of checkpoint. If you're not familiar with it, checkpoint is a package to help with reproducible analysis: you give it a particular snapshot date from the MRAN site, and it installs the packages that your project depends on from that snapshot.

Just before the Christmas break, I got a message that it was failing CRAN checks. Specifically, building a vignette was causing a warning that a file was not found. I've made some changes, but the error persists.

This is the snippet of the log with the error. The full log can be found at https://win-builder.r-project.org/incoming_pretest/checkpoint_0.4.8_20200108_065428/Debian/00check.log

Would anyone be able to provide a clue as to what's going on? It seems to be working on Windows, but not on Debian.
