Use this if you are using igraph from R
This function assesses the distance between two community structures.
compare( comm1, comm2, method = c("vi", "nmi", "split.join", "rand", "adjusted.rand") )
Character scalar, the comparison method to use. Possible values: ‘vi’ is the variation of information (VI) metric of Meila (2003), ‘nmi’ is the normalized mutual information measure proposed by Danon et al. (2005), ‘split.join’ is the split-join distance of can Dongen (2000), ‘rand’ is the Rand index of Rand (1971), ‘adjusted.rand’ is the adjusted Rand index by Hubert and Arabie (1985).
A real number.
