listMethods {svMisc}R Documentation

List all methods associated with a generic function or a class

Description

List all S3 and/or S4 methods for a generic function or for a class.

Usage

listMethods(f = character(), class = NULL, S3 = TRUE, S4 = TRUE,
        mixed = TRUE, filter = getOption("svGUI.methods"))

Arguments

f The name of the generic function (character string), used only when class = NULL
class The name of a class
S3 If TRUE, list of S3 methods
S4 If TRUE, list of S4 methods
mixed If TRUE, S3 and S4 methods are mixed together in a character vector, otherwise, S3 and S4 methods are reported separately in a list
filter A list of methods to consider when listing class methods. Only classes in this list that are defined for the class are returned. Store the list of methods you want in the options "svGUI.methods". The package proposes a reasonable starting point on loading if this option is not defined yet.

Value

If mixed = TRUE, a list with components:

S3 The S3 methods for the generic function or the class, or character(0) if none
S4 The S4 methods for the generic function or the class, or character(0) if none

Otherwise, a character vector with the requested methods
