MFDFAplot.fn {RespirAnalyzer}

Function to plot the results of MFDFA analysis

Description

function to plot the results of MFDFA analysis: q-orde fluctuation function, Hurst exponent,mass exponent and multifractal spectrum. The fitting result of binomial multifratcal model can be also shown by the fitting line

Usage

MFDFAplot.fn(
  Result,
  scale,
  q,
  cex.lab = 1.6,
  cex.axis = 1.6,
  col.points = 1,
  col.line = 1,
  lty = 1,
  pch = 16,
  lwd = 2,
  model = TRUE,
  cex.legend = 1
)

Arguments

Result

a list of the MFDFA results.

scale

a vector of scales used to calculate the MFDFA results.

q

a vector, q-order of the moment used to calculate the MFDFA results.

cex.lab

the size of the tick label numbers/text with a numeric value of length 1.The default value is 1.6.

cex.axis

the size of the axis label text with a numeric value of length 1.The default value is 1.6.

col.points

color of the and point.

col.line

color of the line

lty

line types.

pch

points types.

lwd

line width.

model

whether to use the model to fit the results and draw a line of fit.

cex.legend

the size of the legend text with a numeric value of length 1.The default value is 1.

Value

No value returned
