Dear R users,

I want to create a proper .Rd file for the show method for an S4 class.
I am encountering problems in the \usage{} line, I guess. An example:

setClass("testClass",
        representation(a="character"))

setMethod("show", "testClass", function(object){
})


The .Rd file:

\name{show,-method}
\alias{show,testClass-method}
\alias{show}
\title{Show method for testClass...}
\usage{\S4method{show}{testClass}(object)
}
\description{Show method for testClass}
\arguments{\item{testClass}{object}
}

CHECK says:
* checking Rd \usage sections ... WARNING
Undocumented arguments in documentation object 'show,-method'
 object

What would be a correct \usage line? Writing R extensions says:
\S4method{generic}{signature_list}(argument_list)
What am I doing wrong?
It works though if I simply delete the \usage line.
Unfortunately I use roxygen and the line is created automatically,
so I need to create it properly.

Thanks in advance,
Mark
