Odd R CMD Check error in archive vignette.

[dajmcdon]

For some reason, my local R CMD Check errors out on key(x$DT) around line 90 in this vignette (though no problem when build manually).

Potentially intermittent.

I claimed this might be intermittent because I expected the error to be in the GitHub checks rather than a local check and was unable to reproduce, but GitHub check != local check.

I tried a devtools check locally and didn't get any vignette building errors (after I installed gginnards, that is). So maybe it's intermittent, maybe it's system-dependent, maybe I'm still not doing the right thing to try to reproduce.

I'd guess the main issue to be worried about here is that it's system-independent and intermittent, and that we might randomly get weird online docs via pkgdown.

Closing due to issue age and lack of actionable steps.
