Detect components that load heavily on a single channel. Looks for components that have one particular channel that has a particularly high z-score.
ar_chanfoc(data, plot = TRUE, threshold = NULL, verbose = TRUE, measure = "max", ...)
data |
|
---|---|
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". |
