Dear all, I am using the brokerage function in the sna package to look at liaisons between groups. The function returns raw and expected scores by vertex (raw.nli and exp.nli) and the aggregate raw and expected scores (raw.gli and exp.gli). However, I am interested in the scores for each group that I am studying and only the *expected* scores per group (exp.grp) are given, not the raw scores by group. I thought maybe I'd be able to calculate the raw scores by sorting my vertices into groups and summing their raw scores within each group, but exp.grp does not seem to be the sum of exp.nli sorted by group. I would be grateful for any help.
