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")
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, ...)

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

mailto:johannes at huesing.name  from such a trifling investment of fact.
