Yes. Apparently the findAssocs() function is *generic* and there is
at least one *method* for it.
Type methods(findAssocs) to find the list of all available methods.
Then type the name of a particular method to see the code for
that method. E.g. if there is a method "findAssocs.melvin" (which
is the method "dispatched" when you invoke
where "x" is an object of class "melvin") then typing
will show the code for this method.
You should probably read up a bit on S3 methods and objects.
will give you a start.
