Compute SCR latency metrics from event-locked EDA

Estimates onset latency, peak latency, peak amplitude, AUC, and half-recovery latency for each event using a baseline window and response window.

Usage

compute_gazepoint_scr_latency(
  data,
  events,
  time_col = NULL,
  eda_col = NULL,
  event_time_col = NULL,
  event_id_col = NULL,
  group_cols = NULL,
  baseline_window_s = c(-1, 0),
  response_window_s = c(0, 5),
  onset_threshold = 0.01,
  recovery_fraction = 0.5
)

Arguments

data

Data frame containing EDA/GSR samples.

events

Event table or numeric event times.

time_col

Time column in data.

eda_col

EDA/GSR column.

event_time_col

Event-time column.

event_id_col

Event identifier column.

group_cols

Optional grouping columns used to match events to samples.

baseline_window_s

Two-element baseline window relative to event.

response_window_s

Two-element response window relative to event.

onset_threshold

Minimum increase above baseline used for onset.

recovery_fraction

Fraction of peak amplitude used for recovery time.

Value

Data frame with one row per event.
