[R] image() or plotting functions or something else broken in 2.0.1 on OS X?

[Jenny Fox]

Hello.

I just upgraded to 2.01 on Mac OS 10.3.6.  I used to use the image() 
function in 1.9.x.  Now, running the example code from the image() help 
page gives me the following error:

 > x <- y <- seq(-4*pi, 4*pi, len=27)
 > r <- sqrt(outer(x^2, y^2, "+"))
 > image(z = z <- cos(r^2)*exp(-r/6), col=gray((0:32)/32))

lockFocus], AppKit.subproj/NSView.m:2746
2004-12-02 10:35:27.817 R[2649] *** NSTimer discarding exception 
'NSInternalInconsistencyException' (reason '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 3b9a60 and 
selector 'runRELP:'

And then R quits unexpectedly.

I ran the demo(graphics) and it ran fine.  But then I tried to run 
coplot() independently of the demo and I got the same error:

 > ## Tonga Trench Earthquakes
 > coplot(lat ~ long | depth, data = quakes)

window') that raised during firing of timer with target 3b9a60 and

I'm not sure what I'm doing wrong - a quartz window appears when I run 
the command, so it should in fact have a "corresponding platform 
window".

Any advice would be appreciated.
