R Documentation

Register an s3 method

Description

This is a reimplementation of vctrs::s3_register(), implemented here to avoid having to take a dependency on vctrs.

Usage

s3_register(generic, class, method = NULL)

Arguments

generic

Name of the generic in the form pkg::generic.

class

Name of the class

method

Optionally, the implementation of the method. By default, this will be found by looking for a function called generic.class in the package environment.

Note that providing method can be dangerous if you use devtools. When the namespace of the method is reloaded by devtools::load_all(), the function will keep inheriting from the old namespace. This might cause crashes because of dangling .Call() pointers.
