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

<pre><code>&gt; Sys.setenv(LANG = "fr")
&gt; 2 + x
Erreur : objet 'x' introuvable
&gt; Sys.setenv(LANG = "en")
&gt; 2 + x
Error: object 'x' not found
</code></pre>

A list of the abbreviations can be found <a href="http://en.wikipedia.org/wiki/ISO_639-1">here</a>.

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

In the case of RStudio for Windows I succeeded in changing the language following the instructions found in <a href="http://cran.r-project.org/bin/windows/base/rw-FAQ.html#I-want-R-in-English_0021" rel="noreferrer">R for Windows FAQ</a>, in particular I wrote:

<pre><code>language = EN
</code></pre>

inside the file <code>Rconsole</code> (in my installation it is <code>C:\Program Files\R\R-2.15.2\etc\Rconsole</code>); this works also for the command <code>Rscript</code>.

For example you can locate the <code>Rconsole</code> file with this two commands from a command prompt:

<code>cd \</code>

<code>dir Rconsole /s</code>

The first one make the root as the current directory, the second one looks for the <code>Rconsole</code> file.

In the following screenshot you have that <code>Rconsole</code> file is in the folder <code>C:\Program Files\R\R-3.4.1\etc</code>.

You may have more than one location, in that case you may edit all the <code>Rconsole</code> files.

<a href="https://i.stack.imgur.com/32K7U.png" rel="noreferrer"><img src="https://i.stack.imgur.com/32K7U.png" alt="enter image description here"></a>

After that you can open the <code>Rconsole</code> file with your favorite editor and look for the line <code>language =</code> and then append <code>EN</code> at the end of that line.

In the following screenshot the interesting line is the number 70 and you have to append <code>EN</code> at the end of it.

If you are interested in changing the behaviour of functions that refer to one of these elements (e.g <code>strptime</code> to extract dates), you should use <code>Sys.setlocale()</code>.
See <code>?Sys.setlocale</code> for more details.

If you want to change R's language in terminal to English forever, this works fine for me in macOS:

Open terminal.app, and say:

<pre><code>touch .bash_profile
</code></pre>

Then say:

<pre><code>open -a TextEdit.app .bash_profile
</code></pre>

These two commands will help you open ".bash_profile" file in TextEdit.

Add this to ".bash_profile" file:

<pre><code>export LANG=en_US.UTF-8
</code></pre>

Then save the file, reopen terminal and type <code>R</code>, you will find it's language has changed to english.

If you want language come back to it's original, just simply add a <code>#</code> before <code>export LANG=en_US.UTF-8</code>.

You just have to go to your Rapp in your application Folder, right click, show package content then /contents/Resources/. There are the language files e.g. English.lproj or in my case de.lproj wich I deleted. After restarting R, error messages appear in English..

load the language package you want to use and change the options. but take care, this will change also your keyboard layout!
