plot-WspecMat

Plotting WspecMat objects

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.
