Extract standardized sliding-window process features

Description

Extract standardized sliding-window process features

Usage

extract_process_windows(
  data,
  person = "person_id",
  trial = "trial_id",
  time = "time_ms",
  spec = process_window_spec(),
  align_time = NULL,
  pupil = "pupil_bc",
  pupil_tonic = "pupil_tonic",
  pupil_phasic = "pupil_phasic",
  gaze_x = "x",
  gaze_y = "y",
  aoi = "aoi",
  valid_gaze = "valid_gaze_prop",
  valid_pupil = "valid_pupil_prop",
  blink = "blink",
  trackloss = "trackloss"
)

Arguments

data	Sample-level eye-tracking/pupil data.
person, trial, time	Identifier/time columns.
spec	Window specification.
align_time	Optional column containing the alignment event time in the same units as 'time'. Required for response/custom alignment unless 'time' is already relative to the desired origin.
pupil	Optional pupil signal column.
pupil_tonic, pupil_phasic	Optional decomposed pupil columns.
gaze_x, gaze_y	Optional gaze coordinates.
aoi	Optional AOI-state column.
valid_gaze, valid_pupil	Optional validity columns/indicators.
blink, trackloss	Optional blink/trackloss indicators.

Value

An 'eye_process_windows' object.
