[R] setMethod confusion

[Stephen Henderson]

---sorry to repost I sent it as HTML last time---

Hello I've checked through previous postings but don't see a fully
equivalent problem-just a few hints.
I have been trying to set a new method for the existing function "table"
or "as.data.frame.table" for my class "tfSites".
Taking out all the useful code and just returning the input class I get
the error 

>setMethod("table", "tfSites", function(.Object) .Object)

Error in conformMethod(signature, mnames, fnames, f) : 
In method for function "table": formal arguments omitted in the method
definition cannot be in the signature (exclude = "tfSites")

 
>setMethod("as.data.frame.table", "tfSites", function(.Object) .Object )

Error in conformMethod(signature, mnames, fnames, f) : 
In method for function "as.data.frame.table": formal arguments omitted
in the method definition cannot be in the signature (x = "tfSites")

What does this mean? Is there something peculiar about the table
function? Is it because it takes arguments beginning table(..., etc)

Thanks In Advance
