Get or set the language used by expoquimR

expoquimR supports English ("en", default) and Spanish ("es"). The active language controls the language of function output messages, column labels returned by high-level wrapper functions, and error/warning messages. It does not affect the Shiny apps, which have their own in-app language selector.

Usage

expoquimr_lang(lang = NULL)

Arguments

lang

Character. "en" (English, default) or "es" (Spanish). If NULL, returns the currently active language without changing it.

Value

Invisibly returns the previously active language.

Details

The active language is stored in a private package environment, not in options(), so calling this function never alters the user's global R session settings.

Examples

expoquimr_lang()          # query current language
#> Current expoquimR language: en
old <- expoquimr_lang("es")  # switch to Spanish, saving the previous value
expoquimr_lang(old)          # restore it
