[R-pkg-devel] fate of functions with periods in name

I have not introduced functions with periods in their name before, but
recently I wanted to put a new version of "rbind.fill" in my package
rockchalk.  When I do the package check with R-3.5.1, I see a package
build warning:

Found the following apparent S3 methods exported but not registered:
  rbind.fill
See section ?Registering S3 methods? in the ?Writing R Extensions? manual.

It is a function named "rbind.fill", not a method, obviously.

My CRAN interactions lately give me the idea that Warnings ought to be
treated like Errors.  I'll rename my function rbindFill to silence the
warning, but I wonder if I'm actually required to do so.
