[R-pkg-devel] checking S3 generic/method consistency ... NOTE‏

[Gavin Simpson]

Hi Daniel

You should only neee

#' @export

in your roxygen markup as roxygen (well recent versions anyway) are able to
do the right thing and work out what needs to go into the NAMESPACE file.
You don't need @method now, except in cases where there is ambiguity about
the method/class, which shouldn;t be the case here.

See: http://r-pkgs.had.co.nz/namespace.html#exports
