the binaries of R for Mac OS X assumes X11 tcltk. You need to start  
the X11 server and either set the DISPLAY var to :0 if you use R from  
the command line. R.app sets the DISPLAY var for you.

Unless you build an aqua version of the tcltk R package (i.e. you  
configure R to use Aqua TclTk headers) you always need to have a X11  
window server running (like on Linux, I would say).
