[igraph] Using Multilevel.Community to do Basic Network Detection?

[Aaron Weiss]

I’m trying to find the right igraph function (or combination of functions) to identify multiple, disconnected networks within large transactional datasets (where Entity1 is linked to Entity2 via a payment).  I have been playing with multilevel.communities, but I’m not sure this function – or any community detection function – is the right tool. 

 

I do not want to identify clusters or subgroups with networks; I simply want to detect entity membership at the network level, regardless of that network’s structure, clustering, etc.  Ideally, I’d like to be able to specify that networks with fewer than XXX entities/nodes/vertices be excluded, but that is a separate consideration.

 

Any advice is appreciated.

 

Best,

Aaron
