standardGeneric {base} R Documentation

## Formal Method System – Dispatching S4 Methods

### Description

The function 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.

### Usage

standardGeneric(f, fdef)


### Arguments

 f The name of the generic. fdef The generic function definition. Never passed when defining a new generic.

### Details

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.
