concor_hca(m0, cutoff = 0.999, max.iter = 25, p = 1)

concor(m0, cutoff = 0.999, max.iter = 50)

block_names(p_list)

Arguments

m0

A list of n x n matrices, each of which refers to a relation on a set of vertices. Only one-mode data are supported at present.

cutoff

A value between 0 and 1 used to determine convergence.

max.iter

An integer representing the maximum number of iterations.

p

An integer representing the desired number of partitions.

Value

A data.frame depicting the block assignment for each vertex. Rows are sorted to match the order in which vertices appear in the original data. The column vector indicating block membership can be passed directly to the blockmodel command in sna.
