It looks to me like your DISPLAY environment variable is just not set.
You can fix that by setting it to "localhost:0" in your shell
initialization file and then launching either X11 or Carbon emacs from
your shell.  Also, note that the pty bug has been fixed in Panther.
And finally, according to the documentation of R 1.8.0, Aqua and X11
are now supported with a single executable.  I haven't gotten around
to trying it yet, but apparently quartz() is also supported.
