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.
string(x, encoding = NULL)
A character vector or a vector or list of string-like objects.
If non-null, set an encoding mark. This is only declarative, no encoding conversion is performed.
# 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)#>  "UTF-8"as_bytes(cafe)#>  63 61 66 c3 a9# 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)#>  "latin1"as_bytes(cafe_latin1)#>  63 61 66 e9
