I have the same question.  Although, I notice the section Paul linked
to above has something at the end that might explain it...

If you don't like the X11 style of widgets and use command-line R you
would probably want to build R using the Aqua version of Tcl/Tk (see
the `R Installation and Administration Manual'). Note, however, that
such builds do not work when used in the R.app GUI.

However, after reading RTFM, I don't see what they mean.  There is 
this no reference to Aqua that I can find.  However, if you download
the R source code, you will see that there is a configure option 
--with-aqua  Is this what it takes to avoid XQuartz? 

Thanks,

Rodney
