Split a vector into chunks

Question

I have to split a vector into n chunks of equal size in R. I couldn\'t find any base function to do that. Also Google didn\'t get me anywhere. Here is what I came up with so

Answer 1

Using base R's rep_len:

x <- 1:10
n <- 3

split(x, rep_len(1:n, length(x)))
# $`1`
# [1]  1  4  7 10
# 
# $`2`
# [1] 2 5 8
# 
# $`3`
# [1] 3 6 9

And as already mentioned if you want sorted indices, simply:

split(x, sort(rep_len(1:n, length(x))))
# $`1`
# [1] 1 2 3 4
# 
# $`2`
# [1] 5 6 7
# 
# $`3`
# [1]  8  9 10
