s3_register: Register an s3 method

In vegawidget/vegawidget: 'Htmlwidget' for 'Vega' and 'Vega-Lite'

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.

Value

Invisible NULL, called for side effects.
