[Rd] quieting the "apparent S3 methods" warning

Dear All,

I have a similar issue that I would like to resolve before submitting a new
version of a package to CRAN: I have a "pander" S3 method and a function
called "pander.return", which a wrapper around the first (capturing the
output of "pander"). Now I'm aware of the fact, that it should have been
called rather "pander_return", but this decision was made 3 years ago, and
I cannot rename it without breaking functionality in the depending packages.

Is there any way in the means of added roxygen tag, direct edits to the Rd
or NAMESPACE file so that I can remove the "Found the following apparent S3
methods exported but not registered" NOTE from "R-devel CMD check

Thank you,
