Hi all,
I have two matrices which look as following:
Matrix A: 14*14 with weighted edges.
Matrix B: 14*14 where I changed all the weighted edges with 1.
I wanted to check whether igraph results are correct but I can't figure out the
explanations to the following problem:
GraphA <- graph.adjacency(MatrixA, mode=c("directed"),weighted = NULL )
Betweenness <- betweenness ( GraphA, directed = TRUE,
weights = NULL, normalized=TRUE)
GraphB <- graph.adjacency(MatrixB, mode=c("directed"), weighted= NULL)
BetweennessN <- betweenness ( GraphB, directed = TRUE,
weights = NULL, normalized=TRUE)
from which I should get exactly the same results as I specify weighted=NULL but
indeed the results are different one from the other.
I have tried to remove 'normalized' argument to see whether it is biased but I
get different results as well...
Any thoughts?
Thank you very much for your help!!
Marko
