Construct a feature set from features available in currently loaded packages. Lists of available features can be found in the following pages:
Features by package
Features by tag
feature_set(pkgs = NULL, tags = NULL)The package(s) from which to search for features. If NULL,
all registered features from currently loaded packages will be searched.
Tags used to identify similar groups of features. If NULL,
all tags will be included.
Features can be registered for use with the feature_set() function using
register_feature(). This function allows you to register a feature along
with the tags associated with it. If the features are being registered from
within a package, this feature registration should happen at load time using
[.onLoad()].
