All great here. I have added a small rewording in the argument documentation of the plotVolcano and plotMeanDiff functions, feel free to revert if you prefer to original wording.
I also got all green tests under arm64. The coverage of plotPairs.R (based on covr::report()) is incomplete, but the output makes no sense (e.g. it is calling smoothscat 15 times, but the sole expression in the function body is reported as uncovered), so I think there is not much we can do and this is probably an issue in covr, rather than a true positive.

Yes, I'm also not sure what's happening with the coverage in plotPairs (I think it was always off, so not related to this change). Agree with the rewording, will merge once the checks have run.
