\usage{
networkplot(R, groups = NULL, group_label = NULL, title = NULL)
}
\arguments{
\item{R}{A square numeric matrix with names columns and rows}

\item{groups}{Optional data.frame mapping nodes to groups}

\item{group_label}{Optional string labeling the kind of grouping}

\item{title}{Optional plot title}
}
\value{
A ggraph object
}
\description{
Draw an undirected graph from a square matrix
where each variable is a node and the pairwise
entries are the strength of the relationship
(ex: correlation, partial correlation).
