Re: [igraph] assortativity.nominal

[Gábor Csárdi]

Hi,

create a factor and supply it in the 'types' argument. E.g. 

g <- graph.ring(10)

types <- rep(c("odd", "even"), length.out=vcount(g))

assortativity.nominal(g, factor(types))

# [1] -1

Just make sure that the order of the factor corresponds to the order of your vertices.

Hello,

I would like to get the degree of assortativity in a network based on certain categorical attributes of the nodes e.g. nodes in the network have various attributes like sex, profession, education etc. I would like to know to what extent the network is assortative based on these attributes.

I tied using the assortativity.nominal function in igraph but I am not sure where I should specify the nominal variable in the script.

Thanks in advance for the help.

Regards,

renuka
