Hi gabor, here is how I import the matrix and calculate the betweenness.
TabA <- read.csv("~/Desktop/DATI TOTALI/MATRICI INIZIALI/2006/T1_011
copia.TXT")
network <- as.matrix ( TabA )
networkg <- graph.adjacency ( network, mode=c("directed"), weighted = TRUE
)
networkbet <- betweenness ( networkg, directed = TRUE, weights = E (
networkg )$weight )
is it ok now or you need something else?
thanks
Marko
