The rOpenSci R-universe is a bit special as, compared to other R-universes, it builds docs for all the packages in our suite.
Looking at the dashboard helps us identify failures in building the packages as well as in building the pkgdown websites.
We then help authors fix these issues in order to comply with our package curation policy.
As a package author you should also rely on continuous integration in your own repo for catching e.g. R CMD check problems.
Following one of our latest rounds of monitoring, we summarize some common and less common mistakes.
Many of them are not specific to our build system.
This is a companion discussion topic for the original entry at https://ropensci.org/blog/2022/01/31/package-build-failures/
