RHRV (version 5.0.0)

PlotPowerBand: Plots power determined by CalculatePowerBand function

Description

Plots the power of the heart rate signal at different bands of physiological interest.

Usage

PlotPowerBand(
  HRVData,
  indexFreqAnalysis = length(HRVData$FreqAnalysis),
  normalized = FALSE,
  hr = FALSE,
  ymax = NULL,
  ymaxratio = NULL,
  ymaxnorm = 1,
  Tags = NULL,
  Indexes = NULL,
  Tag = NULL,
  verbose = NULL
)

Arguments

HRVData

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

indexFreqAnalysis

Numeric parameter used to reference a particular frequency analysis

normalized

Plots normalized powers if TRUE

hr

Plots heart rate signal if TRUE

ymax

Maximum value for y axis (unnormalized plots)

ymaxratio

Maximum value for y axis in LF/HF band (normalized and unnormalized plots)

ymaxnorm

Maximum value for y axis (normalized plots)

Tags

List of tags to specify which episodes, as apnoea or oxygen desaturation, are included in the plot. Tags = "all" plots all episodes present in the data.

Indexes

List of indexes to specify which episodes (see ListEpisodes), are included in the plot. Indexes = "all" plots all episodes present in the data.

Tag

Deprecated argument, use Tags instead

verbose

Deprecated argument maintained for compatibility, use setVerbose() instead

if (FALSE) {
# Reading a wfdb register and storing into a data structure:

# Filtering heart rate signal:

# Interpolating heart rate signal:

# Calculating spectrogram and power per band:
md = CreateFreqAnalysis(md)

                        shift = 10, sizesp = 1024)
