This allows redrawing 24 to occur following an editing operation. 25 26 This display list could get very large so it may be useful to 27 turn it off in some cases; this will of course disable redrawing. 28 29 All graphics output is also recorded on the main display list 30 of the R graphics engine (by default). This supports redrawing 31 following a device resize and allows copying between devices. 32 33 Turning off this display list means that grid will redraw from its 34 own display list for device resizes and copies. This will be slower 35 than using the graphics engine display list. 36} 37\value{ 38 None. 39} 40\author{Paul Murrell} 41 42\section{WARNING}{ 43 Turning the display list on causes the display list to be erased! 44 45 Turning off both the grid display list and the graphics engine 46 display list will result in no redrawing whatsoever. 47} 48\keyword{dplot} 49
