irep: Create a repeating iterator

In itertools: Iterator Tools

Description

Create an iterator version of the rep function.

Usage

irep(iterable, times, length.out, each)

Arguments

iterable	The iterable to iterate over repeatedly.
times	A vector giving the number of times to repeat each element if the length is greater than one, or to repeat all the elements if the length is one. This behavior is less strict than rep since the length of an iterable isn't generally known.
length.out	non-negative integer. The desired length of the output iterator.
each	non-negative integer. Each element of the iterable is repeated each times.

Examples

unlist(as.list(irep(1:4, 2)))
unlist(as.list(irep(1:4, each=2)))
unlist(as.list(irep(1:4, c(2,2,2,2))))
unlist(as.list(irep(1:4, c(2,1,2,1))))
unlist(as.list(irep(1:4, each=2, len=4)))
unlist(as.list(irep(1:4, each=2, len=10)))
unlist(as.list(irep(1:4, each=2, times=3)))
