[R-SIG-Mac] Setting locale for running R in emacs / ess

[Rainer M Krug]

Hi

I installed R via homebrew, but it should be the same for the normal R
installation.

When I start R in emacs, I get these unset locale warnings:

,----
| During startup - Warning messages:

| 2: Setting LC_COLLATE failed, using "C" 
| 3: Setting LC_TIME failed, using "C"

| 5: Setting LC_MONETARY failed, using "C"

But I have the following in my .emacs file which should set the locales
(as far as I know)

,----
| (setq utf-translate-cjk-mode nil) ; disable CJK coding/encoding (Chinese/Japanese/Korean characters)
| (set-language-environment 'utf-8)
| ;; (set-keyboard-coding-system 'utf-8-mac) ; For old Carbon emacs on OS X only
| (setq locale-coding-system 'utf-8)
| (set-default-coding-systems 'utf-8)
| (set-terminal-coding-system 'utf-8)
| (unless (eq system-type 'windows-nt)
|   (set-selection-coding-system 'utf-8))
| (prefer-coding-system 'utf-8)
`----

which apparently does not work.

Do I have to resort to setting the locales as described at
http://stackoverflow.com/questions/30264526/why-does-my-ess-r-session-fall-back-to-c-locale

or am I missing something?

Thanks,

Rainer
