[Rsiena-help] cross-network effects

[Ruth M. Ripley]

Dear Guido,

Basically, create the networks as normal, defining the node sets because 
you have a two-mode network. Then include both networks in the call to 
sienaDataCreate().

eg

friends1 <- as.matrix(read.table('friends_1.net'))
friends2 <- as.matrix(read.table('friends_2.net'))
projects1 <- as.matrix(read.table('projects1_r.net'))
projects2 <- as.matrix(read.table('projects2_r.net'))

friendship <- sienaNet(array(c(friends1, friends2), dim=c(75, 75, 2)), 
nodeSet="Friends")
projects <- sienaNet(array(c(projects1, projects2), dim=c(75, 60, 2)),
type='bipartite', nodeSet=c('Friends', 'Projs'))

Friends <- sienaNodeSet(75, 'Friends')
Projs <- sienaNodeSet(60, 'Projs')

mydata <- sienaDataCreate(friendship, projects, nodeSets=list(Friends, Projs))
myeff <- getEffects(mydata)

If you are using the siena01gui, just include two networks in the session.

Please let me know if this is not clear or it does not work (I adapted it 
so it is possible there are typos!).

Regards,

Ruth
