I don't think these errors with xfun::isFALSE() are anything in PEcAn—the error is more likely coming from an old version of rmarkdown or knittr or something (not exactly sure, because Yihui doesn't really say where exactly the error comes from in his blog post). When I've seen this error, I've been able to fix it just by using recent versions of packages. For example, the vignettes for PEcAn.DB are built without error here: https://github.com/Aariq/PEcAn.DB/actions/runs/6641355603/job/18043682007#step:6:42. The vignettes also build locally just fine without throwing this error (if you have reasonably up-to-date packages, I guess).

Closing since dropping support for R 4.0 seems to have ~fixed this.
