Q&D function to list all objects with the specified class attribute .
This is one of the author's collection of
ls* Q&D functions. Since anyone can define a new class at any time, there is no predefined set of legal or illegal class names. Remember that an
object can have multiple
classes. This function only allows searching for a single class name in a given call.
The name of the class you're looking for.
A vector of character strings containing the names of matching objects (as would be returned by the base function
ls ) .
