trellis.device: Initializing Trellis Displays

Description

trellis.device initializes a Trellis display device with appropriate settings of the graphics control parameters.

Usage

trellis.device(device = getOption("device"),
               color = !(dev.name == "postscript"),
               theme = lattice.getOption("default.theme"),
               new = TRUE,
               retain = FALSE,
               ...)
canonical.theme(name, color)
col.whitebg()

Value

canonical.theme returns a list of components defining graphical parameter settings for Lattice displays. It is used internally in trellis.device, and can also be used as the theme argument to trellis.par.set, or even as theme in trellis.device to use the defaults for another device.

col.whitebg returns a similar but smaller list.

Details

trellis.device calls the device function to start a display, and sets an appropriate component of the variable lattice.theme (in an unexported environment named .LatticeEnv) to appropriate (device-specific) values. The device specific settings are determined by canonical.theme which returns a list (see below). The settings can subsequently be handled by the interface functions trellis.par.get and trellis.par.set.

col.whitebg returns a similar (but smaller) list that is suitable as the theme argument to trellis.device and trellis.par.set. It contains settings values which provide colors suitable for plotting on a white background. Note that the name col.whitebg is somewhat a misnomer, since it actually sets the background to transparent rather than white.
