Hello:
I'd be happy if any one can tell me how to attach edge weights on
the basis of a connectedness/similarity matrix. Suppose I do the
following for a 3 by 3 correlation matrix
m<- rbind(c(1, 0.2, 0.6), c(0.2, 1, 0.8), c(0.6, 0.8, 1))
m(diag)<-NA;
m[m(a)<0.5] <-0; m[m(a)>=0.5] <-1 #There must be a better way
g<-graph.adjacency(m, mode="upper"] #upper includes diagonals
E(g)$weight ???????
Thanks in advance
