standardGeneric initiates dispatch of S4
methods: see the references and the documentation of the
methods package. Usually, calls to this function are
generated automatically and not explicitly by the programmer.
standardGeneric(f, fdef)standardGeneric dispatches the method defined for a generic
function named f, using the actual arguments in the frame from which
it is called.The argument fdef is inserted (automatically) when dispatching
methods for a primitive function. If present, it must always be the function
definition for the corresponding generic. Don't insert this argument
by hand, as there is no validity checking and miss-specifying the
function definition will cause certain failure.
For more, use the methods package, and see the documentation in
GenericFunctions.
