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

Examples

data("TestData")
Fs=50 ## sampling frequency is 50Hz
Peaks <- find.peaks(Data[,2],Fs,lowpass=TRUE,freq=1,MovingAv=FALSE,
                    W=FALSE,filter=TRUE,threshold=0.05)
PP_interval=diff(Peaks[,1])/Fs
exponents=seq(3, 9, by=1/4)
scale=2^exponents
q=-10:10
m=2
Result <- MFDFA(PP_interval, scale, m, q)
