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'.
||An R graph|
||one or more R graph-style edge names. default NA, in which case all edges in the graph are translated to cy2-style.|
A named list, in with Cytoscape edges names are the content, and bioc graph edge names are their names.
g <- makeSimpleGraph () cy2.edge.names (g) # A~B B~C C~A # "A (phosphorylates) B" "B (synthetic lethal) C" "C (undefined) A" cy2.edge.names (g, R.edge.names="B~C") # B~C # "B (synthetic lethal) C"
