setSClass {methods}R Documentation

Low-level Class definition

Description

This is the lower-level version of setClass. Unless you really know why you are calling it, use setClass instead.

Usage

setSClass(name, properties=list(), extends=character(),
   prototype=NULL, generatorFunction, where=1,
   subclasses=character(), virtual=NA, validity, access)

Arguments

name character string name for the class
properties the representation argument to setClass
extends what classes does this class extend
prototype an object (usually a list) providing the default data for the slots specified in the representation.
generatorFunction an optional function to use in generating new objects from the class
where where to store the resulting definition (as metadata). By default, uses the global environment.
subclasses Classes that extend this class.
virtual Is this known to be a virtual class?
validity, access Optional arguments for validity method and access restrictions. At the time of writing, these are included for compatibility and are not used. In the future, however, the validity method is likely to be relevant. See Programming with Data for its interpretation.
