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")'. _A_u_t_h_o_r(_s): R Development Core Team Maintainer: R Core Team R-core@r-project.org _R_e_f_e_r_e_n_c_e_s: Chambers, John M.
