\title{showIntrGraph: draw interaction matrix on a PCoA plot}
\usage{
showIntrGraph(ela, sa, env = NULL, th = 0, annot_adj = c(0.75, 2))
}
\arguments{
\item{ela}{\link{ELA} output tuple/list (used to obtain stable states etc.; currently
mainly used for context).}

\item{sa}{Parameter set passed to \link{sa2params}.}

\item{env}{target environmental factor.}

\item{th}{Numeric threshold for drawing links (absolute value).}

\item{annot_adj}{Numeric length-2; horizontal/vertical adjustment for labels.}
}
\value{
NULL.
}
\description{
Computes a 2D PCoA embedding from the interaction matrix (\code{jest}) and overlays
interaction links above a threshold \code{th}. Positive and negative links are
drawn separately, and species names are annotated at their coordinates.
