OS X GUI Issue
Yes, the window created in the RQuartz should probably not be created 'deferred' in this case since a CGContextRef won't be available until the window actually appears on a screen.

Hi all,
I'm using the R 2.1.1 framework and the associated R 1.12 Aqua
GUI on OS X Tiger. I think I've found a bug in the GUI. I'm working
with a large dataset (about 400,000 records and 50 variables), and
tried to do a densityplot of one of the variables (with the dataset
attached).
Because the operation takes a minute or two, I hid the R
application using the Cmd-H shortcut, and opened up the Mail
application to check mail. I then minimized the Mail app a minute or
so later, and restored the R application by clicking once on the R
icon in the Dock.
The R app came to the forefront, but the console had the
following error message:
densityplot(~ CurrentBalance | FICO, plot.points = FALSE)
2005-08-08 13:38:03.251 R[2244] *** Assertion failure in -
[RDeviceView lockFocus], AppKit.subproj/NSView.m:3244
2005-08-08 13:38:03.323 R[2244] *** NSTimer discarding exception
'lockFocus sent to a view whose window is deferred and does not yet
have a corresponding platform window' that raised during firing of
timer with target 11dead0 and selector 'kickstart:'
From the contents of the message, I suspect that there might be
a bug with the GUI that occurs when trying to graph using the Quartz
device when the R app is hidden.
Thanks,
Kyle
