Split a vector into chunks

This function either

• splits a vector into n chunks of equal size (type = 1),

• splits a vector into chunks of size n (type = 2).

Usage

chunk_vector(x, n, type = 1, strict = FALSE)

Arguments

x

[atomic()`]
A vector of elements.

n

[integer(1)]
A number smaller or equal length(x).

type

[1 | 2]
Either

• 1 (default) to split x into n chunks of equal size,

• or 2 to split x into chunks of size n.

strict

[logical(1)]
Set to TRUE to fail if length(x) is not a multiple of n, or FALSE (default), else.

Value

A list.
