A class for creating graphical devices, plotting to them etc.

1	Device(filename=NA, restore.parameters=FALSE)

`filename`	A filename where to save the resulting plot. The filename suffix decides what graphical device driver will used. By default the screen will be used.
`restore.parameters`	Some graphical device drivers might change the global graphical parameters (see `par()`). `dev.open()` can restore them automatically if this argument is `TRUE`. Default value is `FALSE` since querying for graphical parameters opens up an annoying empty window if no window is opened.

To set eps/ps or xfig options use .Postscript.Options (see help(.Postscript.Options)). To set bitmap arguments (bmp, jpg/jpeg, png and gif) use .Bitmap.Options. To set default pictex arguments (tex/pictex) use .PicTeX.Options.

Supported devices are screen, eps, ps, bmp, jpg/jpeg, png, tex/pictex, xfig and gif. The gif device requires that ImageMagick (http://www.imagemagick.org/) is installed on the system path. To test if it is installed try system("convert").

The constructor returns a Device object.

	`getOptions`	Get the current default options for a given device type.
	`getParameters`	Gets parameters specific to a certain type of device.
	`getPlotParameters`	-
	`getPrintPath`	Gets the current path where figures are saved.
	`isOpen`	Checks if a device is open or not.
	`new`	Creates a new device.
	`open`	Opens a device.
	`plotRegions`	Static method plotting information about the different regions of a device.
	`plotSymbols`	Display available plot symbols.
	`print`	Prints device to file.
