Starts a graphics device to be used with the Trellis Display functions.
Appropriate parameter settings such as color, symbol and line type are
set for the device.
USAGE:
trellis.device(device = <<see below>>, color = <<see below>>, ...)
OPTIONAL ARGUMENTS:
device
the name of the graphics device to use, this can be a character string
or just the name.
Currently supported devices are:
motif,
postscriptgraphsheetjava.graphpdf.graph
and
wmf.graph
(not all devices are available in all versions of S-PLUS).
If
device is missing,
an appropriate one will be chosen automatically.
color
if
TRUE then
device
will be set up with color parameters,
if
FALSE the device will be set
with monochrome parameters.
By default this is
TRUE for
motif,
java.graph,
and
graphsheet
and
FALSE for
postscript.
Alternatively,
color can be an object specifying the
colors
argument for the
postscript device.
...
additional arguments will be passed to the function
device.
SIDE EFFECTS:
The
trellis.device function starts
a graphics device
and it attaches a list of graphics parameter settings,
named
trellis.setting,
as an attribute to the
.Device object in frame 0.
The Trellis functions access the values in the list for setting
graphical parameters.
The values in the list have been selected to provide good choices
of parameter settings within the capabilities of the device.
