After simulate_from_model has been called, this function can
be used to load one or more of the saved Draws object(s)
(along with RNG information). If multiple indices are provided, these will
be combined into a new single Draws object.
If simulation object is available, it is easier to use the function
draws to load it.
load_draws(dir, model_name, index, more_info = FALSE, simulator.files = NULL)the directory passed to generate_model)
the Model object's name attribute
a vector of positive integers.
if TRUE, then returns additional information such as
state of RNG after calling generate_model
if NULL, then getOption("simulator.files")
will be used.
