The trellis.device
function sets up an R graphics device for
use with lattice graphics, by opening the device if necessary, and
defining a set of associated graphical parameters (colors, line types,
fonts, etc.).
Even if a device is opened without calling trellis.device
, for
example, by calling a device function directly, trellis.device
is still called automatically when a "trellis"
object is
plotted. The default graphical settings used in this case can be
customized using lattice.options
. It is therefore
rarely necessary for the user to call trellis.device
explicitly.
None; trellis.device
is called for the side effect of opening a
device and / or setting associated graphical parameters.
Earlier versions of trellis.device
had a bg
argument to
set the background color, but this is no longer supported. If
supplied, the bg
argument will be passed on to the device
function; however, this will have no effect on the Trellis settings.
It is rarely meaningful to change the background alone; if you feel
the need to change the background, consider using the theme
argument instead.
