[igraph] pagerank using igraph 0.6

[Morais, Ana Sofia]

Hello,

 

Following the recommendation of Tamas Nepusz, I am now using igraph 0.6 to calculate the PageRank of the vertices in a series of graphs. The code runs without any warnings now, but it returns awkward values for one of the graphs. Could it be that I am doing something wrong? Please see the code below.

 

Thanks for your help.

 

Best,

 

Sofia

 

 

m <- matrix (c(0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0), nrow=9, ncol=9)

tm <- t(m)

net = graph.adjacency(tm, mode="directed", weighted=NULL)

pr = page.rank (net, directed = TRUE, damping = 0.85, weights = NA)$ vector
