Copy and Print Devices

From a MS/Windows screen device you can choose from the right mouse button menu to Copy the graphics to the Clipboard as a MS/Metafile or Bitmap format, or else to save the graphics to a file as a Metafile or PostScript file. You can also directly print the graphic from the same menu. This functionality is not available on the X11 screen device under Unix and GNU/Linux.

Having interactively generated a graphic you can copy the graphic to any other device with the dev.copy function. R accomplishes this by keeping a so called display list which tracks the graphics operations used to draw the graphic. When a copy is requested, or the graphics needs to be redrawn, these graphics commands are executed.

The recording of the graphics operations is enabled only for screen devices. The recording to the display list can be turned off, if memory is at a premium:

> dev.control("inhibit")
