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.
