Dear All,
I have two networks. Both the networks have common nodes as well as unique nodes. Is there any way I can combine both and analyze??
Using **R** igraph union:

    library(igraph)
    
    net1 <- graph_from_literal(A-B:C:D, A-C, B-C)
    net2 <- graph_from_literal(A-X:Y:Z, Z-Y)
    
    par(mfrow = c(1, 3))
    set.seed(1)
    plot(net1, vertex.size = 50, main = "net1")
    plot(net2, vertex.size = 50, main = "net2")
    plot(union(net1, net2), , vertex.size = 50, main = "union of net1 and net2")
