\item{group_cols}{Optional grouping columns.}

\item{embedding_dimension}{Embedding dimension for phase-space reconstruction.}

\item{delay}{Delay used in embedding.}

\item{radius}{Radius for recurrence threshold. If \code{NULL}, uses
\code{radius_multiplier * SD}.}

\item{radius_multiplier}{Multiplier used when \code{radius = NULL}.}

\description{
Computes dependency-light recurrence quantification analysis (RQA) features
from IBI/RR intervals. This is intended as a compact nonlinear HRV summary
and not as a clinical diagnostic tool.
