In anespinosa/netmem: Social Network Measures using Matrices

Zone-2 sampling from second-mode

Description

Second-zone multilevel sampling considering a second-mode focal actor

Usage

zone_sample(A, X, ego = TRUE, core = FALSE)

Arguments

A	A symmetric matrix object.
X	X an incidence matrix object.
ego	Whether to add or not ego into the subgraph.
core	Whether to add actors at distance one from ego

Value

This function return a list of second-zone subgraphs using as a focal actor the second-mode of the multilevel network.
