Description

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 or WaveMC object. Redundancy (e.g. same frequencies in each of the periodograms) will be omitted, hence reducing memory consumption.

Details

The subset function “[” extracts the selected elements of slots spec, starts, variance and energy and returns the other slots unchanged.

Objects from the Class

Objects can be created by calls of the form new("Wspec", ...), but regularly they will be created by calls to the function periodogram.

Slots

The following slots are defined. For details see the constructor function periodogram.

freq:

Object of class "numeric".

spec:

Object of class "list".

kernel:

Object of class "ANY".

df:

Object of class "numeric".

taper:

Object of class "numeric".

width:

Object of class "numeric".

overlap:

Object of class "numeric".

normalize:

Object of class "logical".

starts:

Object of class "numeric".

stereo:

Object of class "logical".

samp.rate:

Object of class "numeric".

variance:

Object of class "numeric".

energy:

Object of class "numeric".
