[Paquet, Agnes]

Hi,

I finally managed to make it work (I just needed to have a X11 window
open). 

Thank you very much for your help.

Like Marc, I don't use a Mac either. But the underlying BSD OS
is basically similar to Linux. On Linux, my primary X11 DISPLAY
envvar would be ":0.0", so (at a guess) I suggest you try

  Sys.putenv("DISPLAY"=":0.0")

Hoping this helps!
Ted.
