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.
Attribute ordering of future.chunk.size or future.scheduling can
be used to control the ordering the elements are iterated over, which
only affects the processing order not the order values are returned.
This attribute can take the following values:
index vector - an numeric vector of length nbrOfElements specifying
how elements are remapped
function - an function taking one argument which is called as
ordering(nbrOfElements) and which much return an
index vector of length nbrOfElements, e.g.
function(n) rev(seq_len(n)) for reverse ordering.
"random" - this will randomize the ordering via random index
vector sample.int(nbrOfElements).
