PlotSpectrogram {RHRV}R Documentation

Calculates and Plots spectrogram

Description

Plots spectrogram of the heart rate signal as calculated by CalculateSpectrogram() function

Usage

PlotSpectrogram(Data, size, shift, sizesp = 1024, scale = "linear", verbose = FALSE)

Arguments

Data Data structure that stores the beats register and all the information obtained from it
size Size of window for calculating spectrogram (seconds)
shift Displacement of window for calculating spectrogram (seconds)
sizesp Seconds for calculating spectrogram (zero padding)
scale Scale used to plot spectrogram, linear or logarithmic
verbose Boolean argument that allows to specify if the function returns additional information

Note

An example including all the necessary steps to obtain the power bands of a wfdb register is giving below:

    ## Heart Rate Signal Creation
    md=CreateData(verbose=TRUE)
    md=LoadBeatAscii(md,"register_name",verbose=TRUE)
    md=LoadEpisodesAscii(md,"episodes_file_name",verbose=TRUE)
    md=BuildNIHR(md,verbose=TRUE)
    md=FilterNIHR(md,verbose=TRUE)
    md=InterpolateNIHR(md,verbose=TRUE)
    ## Calculating and Plotting Power per Band
    PlotSpectrogram(md,size=120,shift=10,sizesp=1024,verbose=TRUE)
