This is exactly what happens if you use contract.vertices() with the membership
vector. contract.vertices() expects a vector that tells the "new" ID of each
vertex after the contraction. So, if the value belonging to a certain vertex in
the membership vector is X, then the vertex will be merged into the "new" node
with ID=X in the contracted graph.

Hello everyone. I am new to SNA and learning how to use the igraph package.
I have built a multiplex network from some flat file and would like to
compute couple of metrics on top of that network:
- The number of edge types by node (multiplexity)
- A metric (matrix, contingent table) of edge types association between
the same nodes (e.g: money transfer + good transfer: 20 pairs of nodes;
money transfer + kinship: 120 pairs of nodes)
I have not seen any likely metrics in my web searches. Would I need to
write them ? If yes, is there any available guideline on how to contribute
to igraph ?

Hello, Tam?s
Are you all right?
I wonder if you know how do I run code written in C using RStudio (Windows Vista Operating System and IGRAPH installed with Cygwin)?
Thank you!

Personally, I have no idea -- it's been a while since I used Windows and I have
never used RStudio.
