itertools (version 0.1-3)

irep: Create a repeating iterator

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)))
