ar_chanfoc: Detect high channel focality of ICA components

In kusumikakd/EEG: A collection of utilities for EEG analysis

Description

Detect components that load heavily on a single channel. Looks for components that have one particular channel that has a particularly high z-score.

Usage

ar_chanfoc(
  data,
  plot = TRUE,
  threshold = NULL,
  verbose = TRUE,
  measure = "max",
  ...
)

Arguments

data	eeg_ICA object
plot	Produce plot showing max z-scores and threshold for all ICA components.
threshold	Specify a threshold for high focality. NULL estimates the threshold automatically.
verbose	Print informative messages.
measure	Use maximum "max" or "kurtosis".
...	additional parameters
