SNA clusters description in igraph, R

229 views Asked by At

I have a network with 68,254 clusters in it. I know that the largest cluster has 900k vertices and ~1M edges. And simply by manually looking at other clusters, they seem to have 2 or 3 connected vertices.

Is there a way in R to actually tell you the descriptives of these clusters (preferably excluding the largest one), like average number of vertices, edges, in-, out-degree distribution, density, etc.?

It's a directed graph. I'm using the igraph module for the analysis.

Also, is there a way to sort, say, first 100 clusters decreasing by their vertex count? I'm pretty much a novice with R. Thanks.

I don't know if there is a special function in R to do this. But it's very simple with other packages. You have the network metrics on each of your nodes, each of your cluster should have an ID. You merge this cluster ID on the nodes, and you compute this average number for each metrics. If you are a novice i R, you can even do that with RcmdR.
