[R] defining a method for multiple classes

[Robert M. Flight]

Is it possible to define a method for multiple classes (that are not
simply extensions of the other) without making separate setMethod()
calls?

As far as I understand it, this is how to currently set methods for
multiple classes:

setClass("myClass1", representation=representation(x="numeric",y="numeric"))
setClass("myClass2", representation=representation(x="numeric",z="character"))

setGeneric("x", function(object) standardGeneric("x"))

setMethod("x", signature("myClass1"), function(object) object at x)
setMethod("x", signature("myClass2"), function(object) object at x)


I was wondering if it is possible to do the equivalent of:

setMethod("x", signature(c("myClass1","myClass2")), function(object) object at x)

Or am I always required to do two separate setMethods?

Thanks,

-Robert
