What does this return:

capabilities("X11")

If you are on .Platform$OS.type == "windows" then you may need to do some further research. I doubt that X11 is installed there by default. But your edit shows that you are on a mac so try this:

names(X11Fonts())
# results on my device 
[1] "serif"        "sans"         "mono"         "Times"       
[5] "Helvetica"    "CyrTimes"     "CyrHelvetica" "Arial"       
[9] "Mincho" 

When I execute X11() at the R command console in the Mac-GUI I get an X11 window and choosing X11/About X11' I see that I have "XQuartz 2.1.6 (xorg-server 1.4.2-apple33)". I am using Leopard (still), but I thought that recent version of Macs installed X11 support by default and I don't remember needing to point R in the right direction to find it either.
