Draw picture of a wavelet

DESCRIPTION

Draw a picture of a wavelet

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'

USAGE

draw(x, ...)

REQUIRED ARGUMENTS

x
an S-PLUS object.

OPTIONAL ARGUMENTS

...
methods may have additional arguments.

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.

SIDE EFFECTS

a plot is created on the current graphics device.
