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)
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 |

function for plotting power bands.
