\title{
cy2.edge.names
}
\description{
Bioconductor graph edges are named, i.e., A~B.  The same edge in the
Cytoscape domain would be 'A (<edgeType>) B', where '<edgeType>' might
be 'phosphorylates' or 'represses'.
}
\usage{
cy2.edge.names(graph, R.edge.names=NA)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{graph}{An R graph}
  \item{R.edge.names}{one or more R graph-style edge names.  default NA,
    in which case all edges in the graph are translated to cy2-style.}
  
}

\value{
A named list, in with Cytoscape edges names are the content, and bioc
graph edge names are their names.
