[igraph] Edge symmetry

[Carlos Eduardo]

Hi,

 

Does Igraph have any command to calculate edge symmetry? For instance, to the edges bellow, [0] and [1] indicate an edge symmetry between vertex 1 and 2. So, considering all network edges, the mentioned edges indicate 50% of symmetry.

 

[0] '1' -> '2'

[1] '2' -> '1'

[2] '1' -> '3'

[3] '3' -> '2'

 

Thanks in advance,

Cadu
