PlotPSD {RHRV}

Plot Spectral Density Estimation

Description

Plot the PSD estimate of the RR time series distinguishing the different frequency bands with different colurs.

Usage

PlotPSD(HRVData, indexFreqAnalysis = length(HRVData$FreqAnalysis),
  ULFmin = 0, ULFmax = 0.03, VLFmin = 0.03, VLFmax = 0.05,
  LFmin = 0.05, LFmax = 0.15, HFmin = 0.15, HFmax = 0.4, log = "y",
  type = "l", xlab = "Frequency (Hz) ", ylab = "Spectrum", main = NULL,
  xlim = c(min(ULFmin, ULFmax, VLFmin, VLFmax, LFmin, LFmax, HFmin, HFmax),
  max(ULFmin, ULFmax, VLFmin, VLFmax, LFmin, LFmax, HFmin, HFmax)),
  ylim = NULL, addLegend = TRUE, addSigLevel = TRUE,
  usePalette = c("#000000", "#E69F00", "#56B4E9", "#009E73", "#F0E442"), ...)

Arguments

HRVData

Data structure that stores the beats register and information related to it.

indexFreqAnalysis

An integer referencing the data structure that contains the PSD analysis.

ULFmin

Lower limit ULF band used for distinguish the ULF band.

ULFmax

Upper limit ULF band used for distinguish the ULF band.

VLFmin

Lower limit VLF band.

VLFmax

Upper limit VLF band.

LFmin

Lower limit LF band.

LFmax

Upper limit LF band.

HFmin

Lower limit HF band.

HFmax

Upper limit HF band.

log

a character string which contains "x" if the x axis is to be logarithmic, "y" if the y axis is to be logarithmic and "xy" or "yx" if both axes are to be logarithmic. Default: "y".

type

1-character string giving the type of plot desired. See plot.default.

xlab

a label for the x axis. See plot.default.

ylab

a label for the y axis. See plot.default.

main

a main title for the plot. See plot.default.

xlim

the x limits (x1, x2) of the plot. See plot.default.

ylim

the y limits of the plot.

addLegend

add a simple legend? Default: True.

addSigLevel

Logical value (only used with the lomb method). If true an horizontal line limiting the significance level is included ( Powers > sig.level can be considered significant peaks). See lsp.

usePalette

A new palette of colors for plotting the frequency bands.

...

graphical parameters. See plot.default.
