Calculate transitivity for all networks in a list

I have 500 random networks stored in a list 

for (x in seq_len(500L)) {
+     gs[[x]] <- erdos.renyi.game(361, 695, type = "gnm")

I am able to calculate the transitivity for each network individually using 

transitivity(gs[[1]])

How do I calculate the transitivity for all the networks and output the values into an excel sheet so as to do some statistical analysis. Anyt thoughts please.

Solution

  • Use an *apply function, specifically sapply or lapply.

    library(igraph)

gs <- list()
for (x in seq_len(500L)) {
  gs[[x]] <- erdos.renyi.game(361, 695, type = "gnm")
}

gs.trans <- sapply(gs, transitivity)
write.csv(gs.trans, file="Graph_transivity.txt")
