You can extract the node names first ( V(g1)$name and so on, possibly in a loop), use standard R functions to find those nodes that you want to keep, then extract the subgraphs corresponding to these nodes from each graph with induced.subgraph(), and finally, take the intersection of the subgraphs.
T. Dear list,
have a list of graphs (igraph format) and I would like to obtain a merge graph, which would be the intersection of those nodes and vertices that are shared a certain percentage trough all the graphs. I know that igraph library has the function graph.intersection() but this function intersect all the vertices and nodes present in all the graphs. Any help would be much appreciated Juan
