R: The length of a string.

str_length {stringr} | R Documentation

## The length of a string.

### Description

Technically this returns the number of "code points", in a string. One code point usually corresponds to one character, but not always. For example, an u with a umlaut might be represented as a single character or as the combination a u and an umlaut.

### Usage

    str_length(string)

### Arguments

`string` | Input vector. Either a character vector, or something coercible to one.

### Value

A numeric vector giving number of characters (code points) in each element of the character vector. Missing string have missing length.

### See Also

`stringi::stri_length()` which this function wraps.

### Examples

    str_length(letters)
    str_length(NA)
    str_length(factor("abc"))
    str_length(c("i", "like", "programming", NA))

    # Two ways of representing a u with an umlaut
    u1 <- "\u00fc"
    u2 <- stringi::stri_trans_nfd(u1)
    # The print the same:
    u1
    u2
    # But have a different length
    str_length(u1)
    str_length(u2)
    # Even though they have the same number of characters
    str_count(u1)
    str_count(u2)
