## Formal Methods and Classes

### Description

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

### Details

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")`.
