Indeed, but I am lazy and like to click on Emacs in my Dock, which does
not employ a shell to start applications. Of course, I could also make
changes to ~/.MacOSX/environment.plist to set the DISPLAY variable, but
again laziness. Testing for the DISPLAY and then setting it when
necessary ensures that the Right Thing always happens no matter how I
choose to launch my copy of emacs (amusingly it also means that console
emacs running R can launch X11 windows).

quartz() is not supported outside of RAqua. It used to be that the
window would open, but without an eventloop you couldn't do anything
with it (focus, resize, drag-n-drop, etc) since Quartz is an in-process
WindowServer (like Windows, unlike X11). These days (R-devel anyway)
quartz() simply refuses to do anything in "Darwin Mode" (the
command-line mode employed by Emacs). I believe it is -in theory-
possible to support things Carbon (Quartz, drag-n-drop, etc) in a
console-type environment---stdin/stdout are still around and attached
in Cocoa/Carbon (you can see this when debugging software in PB/Xcode),
its mostly a matter of restructuring R's event loop to coexist in peace
and harmony with other event loops, AFAIK something thats been on the
radar for some time now.
