The goal of oddnet is to identify anomalous networks from a series of temporal networks.
You can install the development version of oddnet from GitHub with:
In this example we generate a series of networks and add an anomalous network at location 50.

networks <- list()
p.or.m.seq <- rep(0.05, 100)
p.or.m.seq[50] <- 0.2 # outlying network at 50
for(i in 1:100){
gr <- igraph::erdos.renyi.game(100, p.or.m = p.or.m.seq[i])
networks[[i]] <- igraph::as_adjacency_matrix(gr)
