Formal Methods and Classes


Formally defined methods and classes for R objects, plus other programming tools, as described in the references.


This package provides the ‘S4’ or ‘S version 4’ approach to methods and classes in a functional language.

See the documentation entries Classes, Methods, and GenericFunctions for general discussion of these topics, at a fairly technical level. Links from those pages, and the documentation of setClass and setMethod cover the main programming tools needed.

For a complete list of functions and classes, use library(help="methods").
