Sub-group error

[Grace Chen]

Hi GIMME community,

I am running into this error, under subgroup-level search: Error in modularity.igraph(graph.adjacency(sim, mode = "undirected"),  :

  Membership is not a numerical vector.

I thought it had to do with my data setup, but the same error came up when I tried it with the sample data. I think the issue comes from line 241 in determine.subgroups.R: 

sub$modularity  <- modularity(graph.adjacency(sim, mode = "undirected"), sub_mem$sub_membership)

Just to confirm, in both setups (sample data and actual data), the data frame containing the subgroup labels has exactly two columns -- the first of class character and the second integer (the actual grouping label). 

Could someone help me with this error please?

Thanks,

Grace
