vec_poke_n: Poke values into a vector

In tidyverse/rlang: Functions for Base Types and Core R and 'Tidyverse' Features

Poke values into a vector

Description

These tools are for R experts only. They copy elements from y into x by mutation. You should only do this if you own x, i.e. if you have created it or if you are certain that it doesn't exist in any other context. Otherwise you might create unintended side effects that have undefined consequences.

Usage

vec_poke_n(x, start, y, from = 1L, n = length(y))

vec_poke_range(x, start, y, from = 1L, to = length(y) - from + 1L)

Arguments

x	The destination vector.
start	The index indicating where to start modifying x.
y	The source vector.
from	The index indicating where to start copying from y.
n	How many elements should be copied from y to x.
to	The index indicating the end of the range to copy from y.
