Description

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

Usage

1
2
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.
