Dear R-package-devel list members,
I want to introduce several unregistered S3 methods into the cv package
(code at <https://github.com/gmonette/cv>). These methods have the form
coef.merMod <- function(object, ...) lme4::fixef(object)
The object is to mask, e.g., lme4:::coef.merMod(), which returns BLUPs
rather than fixed effects, internally in the cv package but *not* to
mask the lme4 version of the method for users of the cv package -- that
could wreak havoc with their work. Doing this substantially simplifies
some of the code in the cv package.
My question: Is it legitimate to define a method in a package for
internal use without registering it?
This approach appears to work fine, and R CMD check doesn't complain,
although Roxygen does complain that the method isn't "exported"
(actually, isn't registered).
Any advice or relevant information would be appreciated.
Thank you,
John
