| Wspec-class {tuneR} | R Documentation |
Class “Wspec” (Wave spectrums).
Objects of this class represent a bunch of periodograms
(see periodogram, each generated by spectrum)
corresponding to one or several windows of one Wave object.
Redundancy (e.g. same frequencies in each of the periodograms) will be omitted,
hence reducing memory consumption.
The subset function “[” extracts the selected
elements of slots spec, starts, variance and energy
and returns the other slots unchanged.
Objects can be created by calls of the form new("Wspec", ...),
but regularly they will be created by calls to the function periodogram.
The following slots are defined. For details see the constructor function periodogram.
