rlang

set_names

Usage

set_names(x, nm = x, ...)

Arguments

x

Vector to name

nm, ...

Vector of names, the same length as x.

You can specify names in three ways:

  • If you do nothing, x will be named with itself

  • You can supply either a character vector to nm or individual strings in to '...“

  • If x already has names, you can provide a function or formula to transform the existing names.

Details

This is a snake case wrapper for stats::setNames(), with tweaked defaults, and stricter argument checking.

Value

.x with the names attribute set.

Examples

set_names(1:4, c("a", "b", "c", "d"))
set_names(1:4, letters[1:4])
set_names(1:4, "a", "b", "c", "d")

# If the second argument is ommitted a vector is named with itself
set_names(letters[1:5])

# Alternatively you can supply a function
set_names(1:10, ~ letters[seq_along(.)])
set_names(head(mtcars), toupper)
