WspecMat-class {tuneR} | R Documentation |
Class “WspecMat” (Wave spectrums as Matrix).
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("WspecMat", ...)
,
but regularly they will be created from a Wspec
object
by calls such as as(Wspec_Object, "WspecMat")
.
The following slots are defined. For details see the constructor function periodogram
.
