set_language {and}R Documentation

Change the language of the current R environment

Description

Changes the value of the LANGUAGE environment variable.

Returns the value of the LANGUAGE environment variable before it was changed. This allows you to use the following structure to temporarily change the language:

old_language <- set_language("es")
on.exit(set_language(old_language))

Usage

set_language(language)

Arguments

language

A language code.

Codes should should be two or three lowercase letters representing the language, optionally followed by an underscore and two uppercase letters representing a territory. For example, "es" represents Spanish and "en_US" represents American English.

If a territory is specified but there is no specific translation for that territory, translations fall back to the general language. For example, if there are no specific translations for Canadian French, "fr_CA" will fall back to "fr".

If a language is specified but there is no translation for that language, translations generally fall back to English.

If language is an empty string or NULL, the LANGUAGE environment variable is unset.

Value

Returns the pre-existing value of the LANGUAGE environment variable

Examples

# Change language to Korean
set_language("ko")

# Change language to Mexican Spanish, which may fall back to "es"
set_language("es_MX")

# Temporarily set the language to Cantonese
old_language <- set_language("yue")
set_language(old_language)

# Change to an invalid language, which generally falls back to English
set_language("zxx")

# Unset the language environment variable
set_language(NULL)
