Registers an explicit full extension chain for the current R session. The
order of extensions is the S3 dispatch order, from outermost to innermost
extension. For example c(mizerExtB = "1.2.0", mizerExtA = "0.4.1")
dispatches to mizerExtB methods first, then mizerExtA methods, then base
mizer methods.
registerExtensions(extensions, install = FALSE)The active maximal extension chain, invisibly.
A named character vector. Names are extension identifiers.
Values are version strings, installation specifications, or
NA_character_. Installed extensions only participate in S3 dispatch if
they provide an S4 marker class with the same name. NA_character_ entries
are treated as in-development dispatch extensions and mizer creates their
marker classes automatically.
Logical. If TRUE, missing or outdated extension packages are
installed via pak::pkg_install(). Version strings install from CRAN;
other requirement strings (e.g. "user/repo@v1.2.0") are passed directly
to pak and may refer to GitHub, local paths, or any other pak-supported
source.
A session can handle objects whose extension chain is a suffix of the
registered maximal chain. For example, after registering
c(mizerExtB = "1.2.0", mizerExtA = "0.4.1"), objects using only
c(mizerExtA = "0.4.1") are also valid.
For extension packages that register themselves incrementally from .onLoad,
use registerExtension() instead.
registerExtension() for the incremental per-package variant.
