grid.display.list            package:grid            R Documentation

Control the Grid Display List

Description:

     Turn the Grid display list on or off.

Usage:

     grid.display.list(on=TRUE)
     engine.display.list(on=TRUE)

Arguments:

      on: A logical value to indicate whether the display list should
          be on or off.

Details:

     All drawing and viewport-setting operations are (by default)
     recorded in the Grid display list.  This allows redrawing to occur
     following an editing operation.

     This display list could get very large so it may be useful to turn
     it off in some cases;  this will of course disable redrawing.

     All graphics output is also recorded on the main display list of
     the R graphics engine (by default).  This supports redrawing
     following a device resize and allows copying between devices.

     Turning off this display list means that grid will redraw from its
     own display list for device resizes and copies.  This will be
     slower than using the graphics engine display list.

Value:

     None.

WARNING:

     Turning the display list on causes the display list to be erased!

     Turning off both the grid display list and the graphics engine
     display list will result in no redrawing whatsoever.
