Detect artifacts in continuous data — detectArtifacts • PhysioPreprocess

Scans continuous data for artifacts using amplitude or gradient criteria.

Usage

detectArtifacts(
  x,
  method = c("amplitude", "gradient", "joint"),
  threshold = NULL,
  window_sec = 1
)

Arguments

x: A PhysioExperiment object.
method: Detection method: "amplitude", "gradient", or "joint".
threshold: Detection threshold. If NULL, computed as median + 5 * MAD.
window_sec: Detection window in seconds (default: 1.0).

Value

A data.frame with columns: onset (seconds), offset (seconds), channel (index), type (detection method).
