R: Create a string

string {rlang} | R Documentation

## Create a string

### Description

These base-type constructors allow more control over the creation of strings in R. They take character vectors or string-like objects (integerish or raw vectors), and optionally set the encoding. The string version checks that the input contains a scalar string.

### Usage

    string(x, encoding = NULL)

### Arguments

`x` | A character vector or a vector or list of string-like objects.
`encoding` | If non-null, set an encoding mark. This is only declarative, no encoding conversion is performed.

### Examples

    # As everywhere in R, you can specify a string with Unicode
    # escapes. The characters corresponding to Unicode codepoints will
    # be encoded in UTF-8, and the string will be marked as UTF-8
    # automatically:
    cafe <- string("caf\uE9")
    Encoding(cafe)
    as_bytes(cafe)

    # In addition, string() provides useful conversions to let
    # programmers control how the string is represented in memory. For
    # encodings other than UTF-8, you'll need to supply the bytes in
    # hexadecimal form. If it is a latin1 encoding, you can mark the
    # string explicitly:
    cafe_latin1 <- string(c(0x63, 0x61, 0x66, 0xE9), "latin1")
    Encoding(cafe_latin1)
    as_bytes(cafe_latin1)
