Draw mother wavelet or scaling function associated with wst object.
This function draws the mother wavelet or scaling function associated with a wst.object.

This function extracts the filter component from the wst object (which is constructed using the filter.select function) to decide which wavelet packet family to draw. Once decided the draw.default function is used to actually do the drawing.
If the plot.it argument is set to TRUE then nothing is returned. Otherwise, Otherwise, as with draw.default, the coordinates of what would have been plotted are returned.

If the plot.it argument is TRUE (which it is by default) a plot of the appropriate wavelet packet is plotted on the active graphics device.

# Generate some test data

test.data <- example.1()$y
## Not run: ts.plot(test.data)
#
# Now do the \code{packet-ordered non-decimated DWT} of the data using the Daubechies
# least-asymmetric wavelet N=10 (the default arguments in \code{\link{wst}}).
#
tdwst <- wst(test.data)
#
# What happens if we try to draw this new tdwst object?
#
## Not run: draw(tdwst)
#
# We get a picture of the wavelet that did the transform
