Dear R-users,
I am confused about defining S3 methods when objects or methods involve
several dots. Here is my problem.
Package coda defines the following two generic methods:
as.mcmc(x,...)
as.mcmc.list(x,...)
I want to add an S3 method for the second method for my object of class
twDEMC
as.mcmc.list.twDEMC <- function(x,...)
R CMD check then warns:
* checking S3 generic/method consistency ... WARNING
as.mcmc:
function(x)
as.mcmc.list.twDEMC:
function(x, maxLength, thin, start, ...)
See section 'Generic functions and methods' of the 'Writing R
Extensions'
manual.
I also tried to use setMethodS3 from R.oo package:
setMethodS3("as.mcmc.list","twDEMC", function( x, ...){})
I also added "S3method(as.mcmc.list,twDEMC)" to the NAMESPACE file.
However, R CMD check still issues the warning.
How do I tell R (or check??) what is the generic and what the class?
(using Windows XP, R version 2.10.1)
Best regards
