Plotting a spectogram (image) of an object of class Wspec or WspecMat.

Keywords
methods, hplot
Usage
# S4 method for WspecMat,missing
plot(x, xlab = "time", ylab = "Frequency", 
    xunit = c("samples", "time"), log = "", ...)
# S4 method for Wspec
image(x, xlab = "time", ylab = "Frequency", 
    xunit = c("samples", "time"), log = "", ...)
Arguments
x

Object of class WspecMat (for plot) or Wspec (for image).

xlab, ylab

Label for x-/y-axis.

xunit

Character indicating which units are used to annotate the x-axis. If xunit = "time", the unit is time in seconds, otherwise the number of samples.

log

Character - "z" if the z values are to be logarithmic.

Further arguments to be passed to the underlying image function. See image for details.

Details

Calling image on a Wspec object converts it to class WspecMat and calls the corresponding plot function. Calling plot on a WspecMat object generates an image with correct annotated axes.
