Formal Method System Placeholders

Description:

     These routines are primitives used with the `methods' package.
     They should not be used without it and do not need to be called
     directly in any case.

     `standardGeneric': dispatch the method defined for generic
          function named `f', using the actual arguments in the frame
          from which `standardGeneric' is called.

     `objWithClass': return the result of setting the class of `object'
          to `value'.  Defined as a separate primitive function because
          R types cannot generally be changed in place.

     `dataClass': returns a single string for the class of `object'
          even in the case that the object has an old-style class
          attribute with multiple strings.

     `topicName': the string used internally to find documenation of
          the given type and topic.  Called by the `?' operator and the
          special prompt functions in the methods package.

Usage:

     standardGeneric(f)
     objWithClass(object, value)
     dataClass(object)
     topicName(type, topic)
