I just started to play around with igraph and I'd like to use the cohesive.blocks function on a weighted network, but does cohesive.blocks make use the information about edge weights in the computation?
On a related note, is creating a graph object like this: g <- graph( c(0,1, 0,1, 0,2, 1,3)) equivalent to set a weight of 2 to the edge between node 0 and 1?
