fourier_factor: Fourier factor of a wavelet

In wavScalogram: Wavelet Scalogram Tools for Time Series Analysis

Description

This function computes the Fourier factor of a wavelet, according to Torrence and Compo (1998).

Usage

fourier_factor(wname = c("MORLET", "DOG", "PAUL", "HAAR", "HAAR2"),
                      wparam = NULL)

Arguments

wname	A string, equal to "MORLET", "DOG", "PAUL", "HAAR" or "HAAR2" that determines the wavelet function.
wparam	The corresponding nondimensional parameter for the wavelet function (Morlet, DoG or Paul).

Value

The numeric value of the Fourier factor.
