Plot ICA Components

Source: R/eeg-vis.R
eegPlotICA.Rd

Displays ICA component time courses in a stacked layout similar to eegPlotSignal. Optionally shows topographic maps of the mixing matrix weights as a side panel annotation.

Usage

eegPlotICA(
  x,
  components = NULL,
  time_range = NULL,
  show_topography = TRUE,
  assay_name = NULL
)

Arguments

x

A PhysioExperiment object with ICA results.

components

Integer vector of component indices to display. If NULL, the first 10 (or fewer) are shown.

time_range

Numeric vector of length 2 specifying time range in seconds. If NULL, all data is shown.

show_topography

Logical; if TRUE and ICA mixing matrix is available in metadata(x)$ica$mixing, include topographic inset labels.

assay_name

Input assay name. If NULL, uses "ica" if available, otherwise the default assay.

Value

A ggplot2 object.

Examples

if (requireNamespace("ggplot2", quietly = TRUE)) {
  pe <- make_eeg(n_time = 5000, n_channels = 19, sr = 500)
  pe <- eegICA(pe, n_components = 10)
  eegPlotICA(pe, components = 1:5)
}
