This function is generic (see Methods); method functions can be written to handle specific classes of data. Classes which already have methods for this function include: `wd',`imwd',`imwdc'
Graphical parameters may also be supplied as arguments to this function (see par). In addition, the high-level graphics arguments described under par and the arguments to title may be supplied to this function.
