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:

cpt, crystal.list, crystal.vector, decompose, dwt, nd.dwt, rob.dwt, waveshrink, wpt.

stack.plot(x, data=T, ...)
stack.plot.default(x, x.axis=T, y.axis=T, type="l", plot=T,
           bars=F, vgap=.05, grid=F, times=time(x[[1]]),
           grid.lty=par("lty")+1, same.scale=NULL,
           zerocenter=F, zeroline=F, col=rep(1, n), ...)

x:

a list of numerical vectors, missing values are allowed.

data:

for objects of class "decompose", "nd.dwt", or "wpt", data can be either a logical flag or a numeric vector. For objects of class "crystal.list" or "crystal.vector", data must be specified as a numeric vector. If data is logical and data=TRUE, then the inverse transform will be computed and plotted as the first subplot. The argument data is not available with the default method.

x.axis:

logical flag: if TRUE, then the x-axis is plotted.

y.axis:

logical flag: if TRUE, then the y-axis is plotted.

type:

a character or character vector specifying the plotting style for each subplot: see the par function for available types.

plot:

logical flag: if TRUE, the plot is created.

bars:

logical flag: if TRUE, vertical bars are added to the plot on the right hand side to compare the range of the subplots. The vertical bars are all the same absolute length, so a subplot with a very wide bar has a very small dynamic range.

vgap:

number between 0 and 1 indicating the percent of the y range that is the length of the gap between individual plots. The default is .05, or 5% of the y range.

grid:

logical flag: if TRUE grid lines are plotted between each subplot.

times:

a vector of time units used to construct the x-axis.

grid.lty:

integer giving the line type for the grid of crystals. See the lty argument for par.

same.scale:

a logical flag or integer vector. If same.scale is an integer vector, it specifies which resolution levels (crystals) are plotted on the same vertical scale. If same.scale is logical and TRUE, then all levels are plotted on the same scale. By default, all detail coefficients are plotted in the same scale.

zerocenter:

logical flag: if TRUE, the y range for each subplot is centered at zero.

zeroline:

logical flag: if TRUE, a horizontal line at 0 on the y-axis for each subplot.

col:

a numeric value or vector specifying the color for each subplot.

name.style:

one of "filter", or "pretty" indicating the name style used for crystals in the plot, see crystal.names for details. This argument applies only for wavelet packet objects.

Graphical parameters may also be supplied as arguments to this function (see par).
