plot-WspecMat: Plotting WspecMat objects

In tlevine/tuneR: Analysis of music and speech

Description

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

Usage

## S4 method for signature 'WspecMat,missing'
plot(x, xlab = "time", ylab = "Frequency", 
    xunit = c("samples", "time"), log = "", ...)
## S4 method for signature '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.
