addpkt {wavethresh}

Add a wavelet packet box to an already set up time-frequency plot

Description

This function assumes that a high-level plot has already been set up using plotpkt. Given that this function plots a wavelet packet box at a given level, packet index and with particular shading and color and optionally plotting a sequence of coefficients at that location rather than a shaded box.

Usage

addpkt(level, index, density, col, yvals)

Arguments

level

The level at which the box or yvals are plotted

index

The packet index at which the box of yvals are plotted

density

The density of the shading of the box

col

The color of the box

yvals

If this argument is missing then a shaded coloured box is drawn, otherwise a time series of yvals is plotted where the box would have been.
