This is an internal function.
makeChunks(nbrOfElements, nbrOfWorkers, future.scheduling = 1,
future.chunk.size = NULL)(integer) Total number of elements to iterate over.
(numeric) A strictly positive scalar.
Only used if argument future.chunk.size is NULL.
(numeric) The maximum number of elements per
chunk, or NULL. If NULL, then the chunk sizes are given by the
future.scheduling argument.
(integer) Number of workers available.
A list of chunks, where each chunk is an integer vector of
unique indices [1, nbrOfElements]. The union of all chunks
holds nbrOfElements elements and equals 1:nbrOfElements.
If nbrOfElements == 0, then an empty list is returned.
