Hi,   Is there a built in function that returns a character vector of all subclasses of a given superclass? showClass(Class = "SomeClass") contains the info that I want, but I don't know how to access it. getSubClasses <- function(superClass) return(setdiff(getClasses(.GlobalEnv), superClass)) wíll only work if the global enviroment isn;t filled with other class definitions.
