autocurve.edges: Optimal edge curvature when plotting graphs
Description
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.
Usage
autocurve.edges (graph, start = 0.5)
Arguments
graph
The input graph.
start
The curvature at the two extreme edges. All edges will
have a curvature between -start and start, spaced
equally.
Value
A numeric vector, its length is the number of edges in the graph.
Details
autocurve.edges calculates the optimal edge.curved
vector for plotting a graph with multiple edges, so that all edges
are visible.
