| plot-WspecMat {tuneR} | R Documentation |
Plotting a spectogram (image) of an object of class Wspec or WspecMat.
## 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 = "", ...)
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. |
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.
