Hi All,
I am currently analyzing networks using igraph package and calculating
transitivity values.
I am experiencing a problem, that while using code below, when I try to
find weighted transitivity value by changing weights on the edges still the
value of the node remains the same. Is this an expected property of
transitivity implementation (Output is in bold).
Thank you for your help.
Regards
Gaurav Thareja
gw <- graph.formula(A-B:C:D:E, B-C:D, C-D)
E(gw)$weight <- 0.05
E(gw)$color <- "grey"
E(gw)[ V(gw)[name == "B"] %--% V(gw)[name == "C" ] ]$weight <- 0.5
E(gw)[ V(gw)[name == "B"] %--% V(gw)[name == "C" ] ]$color <- "red"
plot(gw)
transitivity(gw, type="weight", vids = "B", isolates = c("zero")) *[1]*
transitivity(gw, type="weight", vids = "C", isolates = c("zero")) *[1]*

plot(gw)
