In Kneerav/biomechanics: A bunch of functions useful in biomechanical analysis

Description

Process raw data to determine residuals between the raw and filtered signal using a range of low pass cutoff frequencies for butterworth filter.

Usage

residual_analysis(raw_signal, cutoff_range = c(0, 20), sample_freq = 1000,
  final_order = 4, interval = 0.01)

Arguments

raw_signal	vector of raw values of which you wish to determine the optimal cutoff frequency.
cutoff_range	numeric vector of format c(lower,upper) containing the lower and upper cutoff frequency limit. Defaults to c(0,20).
sample_freq	numeric value indicating the frequency of the signal. Defaults to 1000Hz.
final_order	numeric value indicating the final order of the filter. Defaults to 4.
interval	numeric value indicating the increment by which the cutoff frequency will increase within the limits specified by cutoff_range. Defaults to 0.01.

Value

dataframe containing the cutoff frequencies and the respective residual at the given cutoff frequency.
