Rainer,

Download exec-path-from-shell.el from:

  https://github.com/purcell/exec-path-from-shell

and place it where you may have other Emacs related add ins.

Then, in your ~/.emacs file, add:

  (load "/PATH.TO/exec-path-from-shell")
  (exec-path-from-shell-initialize)

Replacing PATH.TO with the actual path to the exec-path-from-shell.el file.

You should remove the other lines pertaining to locales that you have above.

That should help Emacs/ESS started from the GUI/dock pick up the environment that you would normally have in a terminal session of R.

Also, in case you are not aware, there is a dedicated ESS list here:
