You need (a) a recent OS X framework build of python, which also installs IDLE (b) a recent OS X framework build of AquaTk (i.e. native Tcl/Tk) (c) a version of R compiled with AquaTk and without X11 (d) a recent version of Rpy Now you can open IDLE and say >> from rpy import * >> r.quartz() >> r.library("tcltk") >> r.demo("tkdensity") This all works. You get the Aqua Tk widgets and the plotting in the quartz device. Windows can be brought to the foreground, minimized to the dock, and widgets can be operated with the mouse. No X11 is required at all. ==Jan de Leeuw; Professor and Chair, UCLA Department of Statistics; Editor: Journal of Multivariate Analysis, Journal of Statistical Software US mail: 9432 Boelter Hall, Box 951554, Los Angeles, CA 90095-1554 phone (310)-825-9550; fax (310)-206-5658; email: deleeuw@stat.ucla.edu homepage: http://gifi.stat.ucla.edu ------------------------------------------------------------------------ ------------------------- No matter where you go, there you are. --- Buckaroo Banzai http://gifi.stat.ucla.edu/sounds/nomatter.au ------------------------------------------------------------------------ -------------------------
