Filter an extension vector to those that participate in S3/S4 dispatch

Description

An extension participates in dispatch if its requirement is NA_character_ (in-development), if an S4 class with its name already exists, or if its loaded package registers S3 dispatch methods for its marker class (see providesDispatchMethods()). The last case lets an installed extension package participate without defining its marker class statically; mizer creates the class dynamically in defineExtensionClasses().

Usage

dispatchExtensions(extensions)

Arguments

extensions

Named character vector of extensions.

Value

A named character vector containing only the dispatch extensions, preserving order.
