[Rd] Documenting newly created generic versions of non-generic base R functions

[Gavin Simpson]

Hi,

Following the Writing R Extensions manual, I created a method for the
cor function. As cor is not a generic, I followed the advice of section
6.1 of the same manual and did the following:

cor <- function(x, ...) UseMethod("cor")
cor.default <- stats::cor
cor.symcoca <- function{ some code }

I used package.skeleton to create the basic set-up of my package,
containing the above functions.

Do I need to provide a .Rd file for cor and cor.default? - seeing as
cor.default is cor currently.

What is the best way to handle documenting functions produced using the
above hi-jack methodology?

Cheers

Gav
