How to get a list of classes that have a common superclass S4 in R

Question

In R, how do I get a list of a subclass of an S4 superclass?

I found showClass ("mySuperClass", complete = FALSE), but it only prints the result. I would like to save it in a vector to use it.

Answer 1

Open the class definition class (the class definition is itself an S4 class!)

cls = getClass("MySuperClass") class(cls) class?classRepresentation 

and, with a little study, come to

 names( cls@subclasses )
