I've just started playing around with the roxygen package and I've very happy with the results so far. However I was wondering, is there a way to specify to roxygen that it should ignore certain functions that are not user-accessible?
Specifically, I'd rather not have a .Rd file pop up because I'm using the .onLoad() hook in my package. This function is already documented in the base package so there's no reason for me to re-document it.
Well, I finally found and browsed the Roxygen-devel list at R-forge to see when this would be implemented, and it appears to already be in the version of Roxygen that is on CRAN. The key is to specify use.Rd2=TRUE when calling roxygenize(). Under this mode, Roxygen will skip creating documentation for any functions that are not preceded by Roxygen comments.
This is on their to do list - in the next version, only functions with roxygen documentation will create man files.
Use the internal keyword field (i.e. @keywords internal) to remove the function from the documentation and make it available for experienced users only.
