Plot EDA Time Series

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

Plots electrodermal activity signals as time series using base R graphics. Multiple channels are displayed in stacked panels. Optionally overlays vertical event markers.

Usage

plotEda(
  x,
  channels = NULL,
  time_range = NULL,
  assay_name = NULL,
  show_events = TRUE,
  main = "EDA Signal",
  col = NULL,
  ...
)

Arguments

x

A PhysioExperiment object containing EDA data.

channels

Integer or character vector specifying which channels to plot. If NULL (default), all channels are plotted.

time_range

Numeric vector of length 2 giving start and end times in seconds for zooming (e.g., c(10, 30)). If NULL, the full signal is plotted.

assay_name

Name of the assay to plot. If NULL, uses defaultAssay(x).

show_events

Logical; if TRUE (default) and events exist, draws vertical dashed lines at event onsets.

main

Character string for the plot title (default: "EDA Signal").

col

Vector of colors for the channels. If NULL, uses default palette.

...

Additional arguments passed to plot().

Value

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