R network package - is there a faster way to add edges? -

i have adjacency matrix (m) of 7000 nodes. creating network using

n <- 7000 m <- matrix(rbinom(3*n, 1, 0.2), n,n) diag(m) <- 0 g <- network(m, directed = f) 

is slow. there more efficient way of creating large random networks in r? alternative methods such using igraph appreciated.

with igraph, can do:

library('igraph') g <- graph.adjacency(m, mode='undirected') 

the edges can retrieved using e(g) , vertices using v(g).

check out igraph docs more information.
