Re: [igraph] page rank edge attributes

[Gábor Csárdi]

Hi, 

it is strength. But this is easy to try, actually:

g <- graph( c(3,1, 3,2, 4,1, 4,2) )

E(g)$weight <- c(1,2, 1,2)

page.rank(g)

#> $vector

#> [1] 0.2748538 0.3742690 0.1754386 0.1754386

and you can see that the PR of 2 is higher, because it receives the stronger edges.

Hi 

I had a query regarding page.rank() function in igraph. 

Are edge weights interpreted as costs or strengths for calculating page rank values of nodes? In other words, a high edge weight value between two nodes is interpreted as a strong tie or weak tie?
