CalculateFracDim: Calculates Fractal Dimension

In RHRV: Heart Rate Variability Analysis of ECG Data

Calculates Fractal Dimension

Description

WARNING: deprecated function. Calculates Fractal Dimension as indicated by Pincus

Usage

CalculateFracDim(HRVData, indexNonLinearAnalysis = length(HRVData$NonLinearAnalysis),
    m = 10, tau = 3, Cra = 0.005, Crb = 0.75, N = 1000, verbose=NULL)

Arguments

HRVData	Data structure that stores the beats register and information related to it
indexNonLinearAnalysis	Reference to the data structure that will contain the non linear analysis
m	Value of the dimension of the expansion of data
tau	Delay of the expansion of data
Cra	Minimum value of correlation for calculating Fractal Dimension
Crb	Maximum value of correlation for calculating Fractal Dimension
N	Number of points of the portion of signal to be analyzed
verbose	Deprecated argument maintained for compatibility, use SetVerbose() instead

Value

Returns HRVData, the structure that contains beat positions register and now associated heart rate instantaneous values also, including the value of the Fractal Dimension

Note

This function is deprecated. We suggest the use of the CalculateCorrDim function instead, which is faster.
