cluster longest paths in a graph using R and igraph












0















I have some undirected graphs which are mostly made up on long strings of vertices. So most vertexes have only two edges, but occasionally these strings of vertices cross/split/merge or loop back on themselves. See example plot:



Graph Plot



I'm trying to identify these long strings using R and igraph but no clustering algorithm in igraph gets it quite right.



I want a clustering algorithm that can identify the longest continuous paths. For example, if a path of length 5 and a path length 7 merge and continue as a path length 9. The algorithm would identify two clusters one of length 7 + 9 = 16 and the other of length 5.

    I'm sure people are more keen to help if you provide a minimal, easily copypasteable example. Cheers
