Error in FUN(): ! Must return a roclet

[chrarnold]

I am getting this error, it literally worked half an hour ago, I dont see what I changed to break this except renaming (exported) functions, and I reproducibly receive this error with the newest 7.3.2 roxygen2 package in Rstudio:

==> devtools::document(roclets = c(''))

I dont find any relevant Google hits, either.

Can be closed. Somehow, my RStudio de-selected roxygen2 in the Project settings, this then caused the error.

The error could be nicer, though, very hard to understand whats the actual reason: It needs to be called with a non-empty list, like this:

==> devtools::document(roclets = c('rd', 'collate', 'namespace'))
