View source: R/calcFrequency.R

Description

Function to estimate the "dominant" frequency of a periodic time series signal.

Usage

1
calcFrequency(series, plot.periodogram = FALSE)

Arguments

series

numeric vector: input vector (time series)

plot.periodogram

logical: whether to plot a periodogram

Details

This function uses Fourier decomposition to determine the 'major' frequency of a time series. Technically this is the frequency of the Fourier component with the highest variance. The function is used by filterTSeriesSSA to determine the frequencies of the individual SSA components.

Value

Frequency of the Fourier component with the highest variance [1/time steps]
