[R] Accessing methods and extending S4 classes of existing packages

[Johannes Huesing]

Dear all,
I am trying to understand how to access S4 methods after loading a 
package, using the online documentation of getMethod and friends.

This is what I have been trying:
> library(coin)
> findMethods("ApproxNullDistribution")
list()
Warning message:
In findMethods("ApproxNullDistribution") :
  nicht-generische Funktion an findMethods() übergeben

whereas in the source of coin I can see the lines: 

setGeneric("ApproxNullDistribution", function(object, ...)
    standardGeneric("ApproxNullDistribution"))

It seems that I am not getting what is going on here. Could anybody
give me a hint?

Greetings


Johannes
