No way to concisely depict networks with bidirectional arrows where each direction differs in strength #90

Closed Spiritspeak closed 5 months ago

Spiritspeak commented 5 months ago

Correlation networks have the advantage that only one edge is drawn between any two nodes; but in some cases the effect from one node to another differs from the reverse, and I'd like to be able to depict that without drawing two edges, since that's half the amount of clutter onscreen. I have tried bidirectional=TRUE, but this creates a single edge that does not contain any information about the individual strength of each edge that is combined into it. Could you add support for this feature?

Hi! A bidirectional edge per definition is a single edge with one weight with two arrowheads. It seems to me you indicate a directed netwokr instead? I don't see how you can show this information without showing two edges. Try parallelEdge = TRUE for a cleaner picture perhaps.
