Using a second monitor, running R under Unix
Thanks, John. This this should be now fixed in the R24-branch (e.g. fetch the installer from http://r.research.att.com tomorrow). It is a quick hack, legacy Quartz windows will now appear in the center of the main screen. In general that device (Quartz in console R) is unsupported and will go away very soon, because it is a legacy from very old times and the API it uses is now deprecated and Apple will remove it from future OS X versions. We are working on a replacement device for R-devel, but it won't work in R 2.4.1, so stay tuned and I'll let you know when it's time to test the new beast ;). Cheers, Simon

I am using a MacBook Pro with Core 2 Duo, with an external screen connected that is set to appear above the MacBook Pro's screen. The laptop's menu appear bar is set to appear at the top of the external monitor. When I run R under ESS, or from the Unix command line, and type quartz (), the graphics window appears to the "left" of the external monitor. Hitting the F9 key brings it into view, but there seems no way to grab it with the mouse and move it onto less ephemeral real estate. [Under R.app, all is well.] [With x11() half the window is off to the left, and I can drag it to anywhere I want (either screen).] A further issue is that when I plot anything on the quartz screen, I get an "error: message, thus:
quartz()
Warning message: quartz() device interactivity reduced without an event loop manager in: quartz()
plot(1:5, 1:5)
CGGStackRestore: gstack underflow. The "CGGStackRestore: gstack underflow" message looks ominous, but it does not cause evident problems. Is there something I can do so that the positioning of the second screen is recognized? At some time in the past, I am sure that quartz () [ and x11()] used to correctly recognize the positioning of the screens. However it is a while since I used quartz(), and I would not have paid too much attention to the x11() behaviour. John Maindonald
