Plot EDA Signal with SCR Peaks

Source: R/eda-plot.R
plotPeaks.Rd

Plots an EDA signal with detected SCR peaks, onsets, and amplitude lines annotated. If no peaks data.frame is supplied, peaks are computed automatically via edaPeaks.

Usage

plotPeaks(
  x,
  peaks = NULL,
  channel = 1,
  time_range = NULL,
  assay_name = NULL,
  main = "SCR Peaks",
  ...
)

Arguments

x

A PhysioExperiment object containing EDA data.

peaks

A data.frame as returned by edaPeaks, or NULL to compute peaks automatically.

channel

Integer or character specifying which channel to plot (default: 1).

time_range

Numeric vector of length 2 giving start and end times in seconds. If NULL, the full signal is plotted.

assay_name

Name of the assay to plot. If NULL, uses "phasic" if available, otherwise defaultAssay(x).

main

Character string for the plot title (default: "SCR Peaks").

...

Additional arguments passed to plot().

Value

Invisible NULL. Called for its side effect of producing a plot.
