curve_multiple {igraph} | R Documentation |
If graphs have multiple edges, then drawing them as straight lines does not show them when plotting the graphs; they will be on top of each other. One solution is to bend the edges, with diffenent curvature, so that all of them are visible.
curve_multiple(graph, start = 0.5)
graph |
The input graph. |
start |
The curvature at the two extreme edges. All edges will have a
curvature between |
curve_multiple
calculates the optimal edge.curved
vector for
plotting a graph with multiple edges, so that all edges are visible.
A numeric vector, its length is the number of edges in the graph.
