[R-SIG-Mac] ERROR in R+Lion+X11: could not find any X11 fonts

[Emilio Molinari]

Hi,

after googling around I surrender and post to this list.
With a Mac OS 10.7.2, R installation 2.14.1, X server starts but doesn't find the fonts.
The solution is not to check xorgs.conf as there is no such config file here.

The behavior is easily spotted:
> plot(1,1)
Error in axis(side = side, at = at, labels = labels, ...) : 
  could not find any X11 fonts
Check that the Font Path is correct.
In addition: Warning messages:
1: In function (display = "", width, height, pointsize, gamma, bg,  :
  locale not supported by Xlib: some X ops will operate in C locale
2: In function (display = "", width, height, pointsize, gamma, bg,  :
  X cannot set locale modifiers
> 
R Graphics: Device 1 (ACTIVE) starts, plot one circle but stops on that error.

Any help for this?
Thank you
