[igraph] Problem Deleting Vertices (and creating Sub-Graphs)

[Ali Ogulcan Ilhan]

Hi,

Thanks a lot, this makes sense, I don’t know why I could not think of it.

If you remove a vertex from the graph, all edges connected to it are also removed. Its degree in the new graph could be smaller than 10.

Dear all,
I have been trying to eliminate vertices with degrees lower than certain thresholds. It should be pretty straightforward but I am having problems. I used the simple code below
mygraph2_3<-delete.vertices(mygraph2, V(mygraph2)[degree(mygraph2) < 10])
Or
e<-degree(mygraph2)
mygraph2_3<-induced_subgraph(mygraph2, v=(e>10))
In either case, when I check the degrees of the remaining vertices there are many with degrees more or less than 10 (and the mean degree for the sub-network is much less than 10). The code does something but I am not sure what it is really doing. All I want to do is to eliminate vertices with degrees less than 10.
Any help is greatly appreciated,
ali ilhan
