In imlijunda/AwkwardMLTools: Awkward ML Tools

The conditions are evaluated only once thus cond() should NOT have side effects.

iterator_batch_cond(x, batch_size = 1L, cond)

iterator_partition_cond(x, part_size = 1L, cond)

`x`	an atomic vector
`batch_size`	batch size
`cond`	a conditional function, must be vectorised.
`part_size`	partition size.

an iterator

x <- runif(n = 50)
f <- function(a) a < 0.8
itr1 <- iterator_batch(x, 3)
itr2 <- iterator_batch_cond(x, 3, f)
collect(itr1)
collect(itr2)
