R: Get names of a vector

names2 {rlang} | R Documentation

## Get names of a vector

### Description

This names getter always returns a character vector, even when an object does not have a `names` attribute. In this case, it returns a vector of empty names `""`. It also standardises missing names to `""`.

### Usage

    names2(x)

### Arguments

`x` | A vector.

### Life cycle

`names2()` is stable.

### Examples

    names2(letters)

    # It also takes care of standardising missing names:
    x <- set_names(1:3, c("a", NA, "b"))
    names2(x)
