loaded | R Documentation |
Each module is stored as an environment inside loaded_mods
with the
module’s code location path as its identifier. The path rather than the
module name is used because module names are not unique: two modules called
a
can exist nested inside modules b
and c
, respectively.
Yet these may be loaded at the same time and need to be distinguished.

loaded_mods
is an environment of the loaded module and package
namespaces.
is_mod_loaded
tests whether a module is already loaded.
register_mod
caches a module namespace and marks the module as loaded.
deregister_mod
removes a module namespace from the cache, unloading
the module from memory.
loaded_mod
retrieves a loaded module namespace given its info.
is_mod_still_loading
tests whether a module is still being loaded.
mod_loading_finished
signals that a module has been completely loaded.
is_mod_still_loading
and mod_loading_finished
are used to
break cycles during the loading of modules with cyclic dependencies.
