Extract heart-rate asymmetry features — extract_gazepoint_hrv

Computes dependency-light heart-rate asymmetry descriptors from IBI/RR intervals, including acceleration/deceleration proportions, signed run summaries, and Guzik-style squared-difference asymmetry.

Usage

extract_gazepoint_hrv_asymmetry(
  dat,
  ibi_col = "IBI",
  group_cols = NULL,
  zero_tolerance = 0
)

Arguments

dat: A data frame containing IBI/RR intervals.
ibi_col: Numeric IBI/RR interval column.
group_cols: Optional grouping columns.
zero_tolerance: Absolute change below which interval differences are treated as zero.

Value

A list with overview, features, run_table, and settings.

Details

Positive IBI/RR differences are treated as decelerations because the heart period lengthens. Negative IBI/RR differences are treated as accelerations.
