ichunk {itertools} | R Documentation |
Create an iterator that issues lists of values from the underlying iterable. This is useful for manually “chunking” values from an iterable.
ichunk(iterable, chunkSize, mode='list')
iterable |
Iterable to iterate over. |
chunkSize |
Maximum number of values from |
mode |
Mode of the objects returned by the iterator. |
# Split the vector 1:10 into "chunks" with a maximum length of three
it <- ihasNext(ichunk(1:10, 3))
while (hasNext(it)) {
print(unlist(nextElem(it)))
}
# Same as previous, but return integer vectors rather than lists
it <- ihasNext(ichunk(1:10, 3, mode='integer'))
while (hasNext(it)) {
print(nextElem(it))
}
