R: Create vectors matching the length of a given vector

vector-along {rlang} | R Documentation

## Create vectors matching the length of a given vector

### Description

These functions take the idea of `seq_along()` and generalise it to creating lists (`list_along`) and repeating values (`rep_along`). Except for `list_along()` and `raw_along()`, the empty vectors are filled with typed `missing` values.

### Usage

    lgl_along(.x)

    int_along(.x)

    dbl_along(.x)

    chr_along(.x)

    cpl_along(.x)

    raw_along(.x)

    bytes_along(.x)

    list_along(.x)

    rep_along(.x, .y)

### Arguments

`.x` | A vector.
`.y` | Values to repeat.

### Examples

    x <- 0:5
    rep_along(x, 1:2)
    rep_along(x, 1)
    list_along(x)
