Re: [igraph] Missing edges in graph objects

[Tamas Nepusz]

Well, it depends on what you want to do with those "missing" edges.
You could add an edge to an igraph graph and then add an edge
attribute named "missing" to it with value=TRUE, but all igraph
algorithms will simply treat this edge as any other edge as they do
not know anything about the semantics of the edge attribute that you
have added. However, you can easily use the "missing" edge attribute
in visualizations - for instance, you could set up the colors of the
edges based on whether the associated "missing" attribute has
value=TRUE or FALSE.
