Description
A convenience feature extraction function that characterises the
frequency spectrum of a given time series in to statistical features
in the frequency domain.
Usage
1
frequency_domain_summary(values, sampling_rate = NA, npeaks = NA)
Arguments
values
A numeric vector from a time series measurement.
sampling_rate
Sampling_rate of values. If NA it uses default
sampling rate of 100Hz.
npeaks
Number of peaks to be computed in emprical wavelet transformation (EWT).
If NA it uses the default value of 3.
Value
A features data frame of dimension 1 x 19. See the
feature definition vignette:
vignette("feature_definitions", package="mhealthtools")
