In teaching I'd like to be able to display a R-graphics window on a wall projection display keeping the R-console on the computer monitor. And so I ask--- Is there a way to move a graphics window out of the Rgui window to a second monitor leaving the R Console window in the Rgui window on the first monitor? Either a Windows or Linux solution would be just fine. --jed diem

Linux: out of the box, Windows: Start RGui with option --sdi, or choose SDI mode in the menu (Edit - GUI preferences ...). Uwe Ligges

Most reasonably new laptops allow the display to show in both places. (There may be limitations on the resolution to accommodate this.) The original question was about showing different things on each monitor: the console visible to the speaker, and graphics visible to the audience. I don't know of any PC laptops that do this, but I think some Macs can. At least that was my interpretation of a minor flap before a presentation at UWO where the projector showed the desktop and the laptop screen showed the stuff the audience was supposed to see. I think to do it on a desktop PC you just need to add an extra video card. Duncan Murdoch

Nearly any modern Windows laptop should be able to "dual head" (the LCD and the display panel/projector, as "adjacent" screens).

PC laptops definitely can, even under XFree86/Linux. (i.e. have the left portion of the "display" be on the LCD, the right portion on the external video-out (connected to a projector/display panel). It is easier to do this on Mac, of course. (it's useful for having notes on the LCD, while the presentation is on the projector, for example). For desktops, you can use 2 video cards (in which case one would usually be a PCI-based, and the other AGP, so the quality may be unequal), but many of the intermediate/expensive video cards ($90US and up, i.e. Radeon 9000) have dual outputs; for about $130 and up, you can actually find dual digitial outputs, which are very nice if you've got digital capable LCD monitors. (or want to do stereoscopic displays, which is why I care...). best, -tony

All dual-headed graphics cards can do this: modern Mac laptops have Radeons, I believe, and PC laptops with the same hardware can do the same things. My 2002 laptop with a Radeon M graphics card certainly can.
