R Documentation

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

Examples

## Not run: 
# Reading a wfdb register and storing into a data structure:
md = CreateHRVData(Verbose = TRUE)
md = LoadBeatWFDB(md, RecordName = "register_name", 
                  RecordPath = "register_path")

# Calculating heart rate signal:md = BuildNIHR(md)

# Filtering heart rate signal:
md = FilterNIHR(md)
# Interpolating heart rate signal:
md = InterpolateNIHR(md)
# Calculating spectrogram and power per band:
md = CreateFreqAnalysis(md)
md = CalculatePowerBand(md, indexFreqAnalysis = 1, size = 120, 
                        shift = 10, sizesp = 1024)
# Plotting Power per Band
PlotPowerBand(md, hr = TRUE, ymax = 700000, ymaxratio = 4)
