trellis.device initializes a Trellis display device with
appropriate settings of the graphics control parameter
trellis.settings.trellis.device(device, color = T, bg, new = T, ...)new = F is specified, then the options for the
current device are changed to the defaults determined by the other
arguments.device
function. See postscript.trellis.device calls the device function to start a
display, sets the global variable trellis.settings to either of
two possible values depending on whether color is set, and
initializes the underlying Grid
display. trellis.settings can subsequently be handled by the
interface functions trellis.par.get and trellis.par.settrellis.par.set, Grid,
