[R-SIG-Mac] GUI from Terminal.app

[Jan de Leeuw]

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.
