Question

My error messages are displayed in French. How can I change my system language setting so the error messages will be displayed in English?

Answer 1

You can set this using the Sys.setenv() function. My R session defaults to English, so I’ll set it to French and then back again:

> Sys.setenv(LANG = "fr")
> 2 + x
Erreur : objet 'x' introuvable
> Sys.setenv(LANG = "en")
> 2 + x
Error: object 'x' not found

A list of the abbreviations can be found here.

Sys.getenv() gives you a list of all the environment variables that are set.
