Classify SCRs into FIR, SIR, and TIR latency intervals — classify_gazepoint_scr

Classifies extracted SCRs into first-, second-, and third-interval response windows based on response latency after stimulus onset.

Usage

classify_gazepoint_scr_intervals(
  dat,
  response_time_col = NULL,
  stimulus_onset_col = NULL,
  latency_col = NULL,
  output_col = "scr_interval",
  latency_output_col = "scr_latency_s",
  fir = c(1, 4),
  sir = c(4, 7),
  tir = c(7, 10)
)

Arguments

dat: A data frame containing SCR events or peaks.
response_time_col: Optional response/peak time column.
stimulus_onset_col: Optional stimulus-onset column. Required when latency_col is not supplied.
latency_col: Optional precomputed latency column.
output_col: Name of the output interval column.
latency_output_col: Name of the latency output column.
fir: Numeric vector of length two defining FIR window in seconds.
sir: Numeric vector of length two defining SIR window in seconds.
tir: Numeric vector of length two defining TIR window in seconds.

Value

A data frame with interval labels and latency metadata.
