Description

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

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.
