__init__.r filesReturn a list of paths to a module<U+2019>s __init__.r files
module_init_files(module, module_path)character string of the fully qualified module name
the module<U+2019>s file path prefix (see Details)
a vector of paths to the module<U+2019>s __init__.r files, in the
order in which they need to be executed, or NULL if the arguments do
not resolve to a valid nested module (i.e. not all of the path components
which form the qualified module name contain a __init__.r file).
The vector<U+2019>s names are the names of the respective modules.
The module_path is the fully qualified module path, but
without the trailing module file (either x.r or x/__init__.r).
