Hello,
I want to generate a 'degree correlation matrix' according to node values y that do not rely on the degree of the nodes.
My toy example:
gg <- erdos.renyi.game (10,0.7)
V(gg)$y <- sample (5,10, replace=TRUE)
I started with ...
edges.gg <- get.edgelist (gg)
mat.y <- matrix (V(gg)$y[
edges.gg[,1]], V(gg)$y[
edges.gg[,2]], nrow=length (V(gg)$y[
edges.gg[,1]]), ncol=2)
... to get the combinations of y values that exist in gg but I dont know how to measure the frequencies. And I did not find a tool in igraph to construct such a 'degree correlation matrix'.
Has anybody an idea?
Thanks
Hermann
