In anespinosa/netmem: Social Network Measures using Matrices

Ego network

Description

Submatrix of ego's neighbourhoods

Usage

ego_net(
  A,
  ego = NULL,
  bipartite = FALSE,
  addEgo = FALSE,
  select = c("all", "in", "out")
)

Arguments

A	A symmetric matrix object
ego	Name of ego in the matrix
bipartite	Whether the matrix is a two-mode network
addEgo	Whether to retain ego in the submatrix or not
select	Whether to consider all sender and receiver ties of ego (all), only incoming ties (in), or outgoing ties (out). By default, all.

Value

This function returns redundancy, effective size and efficincy measures (Burt, 1992).
