Description
A convenience feature extraction function that converts a given
time series in to frequency spectrum and computes energy in each
0.5Hz band from 0 to 25 Hz.
Usage
1
frequency_domain_energy(values, sampling_rate = NA)
Arguments
values
A numeric vector.
sampling_rate
Sampling_rate of values. If NA it uses default
sampling rate of 100Hz.
Value
A features data frame of dimension 1 x 48, each representing energy within
a 0.5Hz band. See the
feature definition vignette:

frequency_energy_features = frequency_domain_energy(
accelerometer_data$x,
sampling_rate = 100.122)
