HHSpectrum {hht} | R Documentation |
Generate Hilbert spectrum
Description
Generates a Hilbert periodogram from the results of Sig2IMF
and EEMD
.
Usage
HHSpectrum(hres, dfreq, freq.span = NULL, time.span = NULL,
scaling = "none", verbose = TRUE)
Arguments
hres |
This is the output generated by |
dfreq |
Frequency resolution of spectrum |
time.span |
Time span to render spectrum over; |
freq.span |
Frequency span to include in spectrum; |
scaling |
If |
verbose |
If |
Details
HHSpectrum
sums Hilbert spectral data over the time domain to produce the equivalent of a periodogram.
The result can be plotted using HHSpecPlot
.
Value
hspec |
A data structure containing the spectrum of each IMF. |
