I was slightly too optimistic. If RGUI is started then .Device is the null device. If you say quartz() then you cannot interact with the graphics window (probably related to the quartz device warning). If you now say library(tcltk) the device is set to quartz and the window comes alive. If the first thing you say is library(tcltk), then the device is automatically set to quartz, and subsequent calls to quartz() are fine.

===If you start R from the terminal and then do non-X11 graphics, you get SetFrontProcess errors. For instance, I have a version of R configured without x11 and with the Aqua version of tcl/tk. If I start this, load tcltk, and do tkStartGUI() I cannot bring the window to the front, because clicking it gives SetFrontProcess errors.
There is, however, a simple way to fix this. Make a copy of R.bin, call it RGUI, then say
/Developer/Tools/Rez -t APPL Carbon.r -o RGUI
and change the name of the R binary in the R startup script from R.bin to RGUI. Then this R will give a tkStartGUI window that you can interact with. The same is true for the tk demos, which now have nice aqua windows you can interact with.
Also, starting quartz() and interacting with the quartz device works fine,
and demos such as tkdensity now display two nicely interacting
aqua windows. Also, you get a working version of Rcmdr in this way.
Thus you have a version of RAqua which does not use the RAqua
GUI but only the terminal. And we have a seemingly reliable way to
use Aqua tcl/tk (and get rid of all of X11). It does not cost anything to add the
Rez command above to the Makefile, and the benefits are huge. There
does not seem to be a need to warn if quartz() is started from the
terminal.
Remains the fact that I have been looking for this solution for two years
and it turns out to be this simple. Must be pretty well hidden. Observe
the Rez command gives RGUI a resource fork and metafile info, also
observe this would not work with Cocoa.
