Minimum/maximum overlap

Two-mode networks can be represented (or 'projected') as one-mode networks.

Usage

minmax_overlap(A, row = TRUE, min = TRUE)

Arguments

A

A matrix object

row

Whether to consider the actors in the rows of the matrix (default) or the column.

min

Whether to extract the minimum (default) or the maximum overlap.

Value

This function return the overlap between the modes (a.k.a. actors, nodes, vertices).
