X11 with aquamacs

I have aqua macs installed.  I would like to use this with a R 2.7.2
that I built on os x 10.3.9.  R works fine in the X11 terminal, but I
can not copy and paste ...  I would like to use aquamacs as my
interface to R.  It starts up fine and interfaces with R preforms
computations,  but when i issue the X11() command it does not open up
a window.  I used the command at the x11 terminal as to the aquamacs
FAQ
export DISPLAY=0.0

then I checked to see if aquamacs recognized to use x11 (I don't
remember the exact command right now) and it returned nil.  So, how do
I get aquamacs to interface with x11.

thanks

make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
