draw.wst {wavethresh} | R Documentation |
This function draws the mother wavelet or scaling function associated with a wst.object
.
draw.wst(wst, ...)
wst |
The wst class object whose associated wavelet or scaling function you wish to draw. |
... |
Additional arguments to pass to the draw.default function which does the drawing. In particular, arguments can be set to choose between drawing the mother wavelet and scaling function, to set the resolution of the plot, to choose between drawing one and two dimensional pictures. |
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.
