R: Poke values into a vector

vec_poke_n {rlang} | R Documentation

## 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`.
