compare

Compares community structures using various metrics


Description

This function assesses the distance between two community structures.

Usage

compare(
  comm1,
  comm2,
  method = c("vi", "nmi", "split.join", "rand", "adjusted.rand")
)

Arguments

comm1

A communities object containing a community structure; or a numeric vector, the membership vector of the first community structure. The membership vector should contain the community id of each vertex, the numbering of the communities starts with one.

comm2

A communities object containing a community structure; or a numeric vector, the membership vector of the second community structure, in the same format as for the previous argument.

method

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).

Value

A real number.
