PlotPowerBand function

Plots power determined by CalculatePowerBand function

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

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

See PlotSinglePowerBand for a more flexible function for plotting power bands.

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)
## End(Not run)
