triad_census_attr: triad census with node attributes

In schochastics/netUtils: A Collection of Tools for Network Analysis

triad census with node attributes

Description

triad census with node attributes

Usage

triad_census_attr(g, vattr)

Arguments

g	igraph object. should be a directed graph
vattr	name of vertex attribute to be used

Details

The node attribute should be integers from 1 to max(attr). The output is a named vector where the names are of the form Txxx-abc, where xxx corresponds to the standard triad census notation and "abc" are the attributes of the involved nodes.

The implemented algorithm is comparable to the algorithm in Lienert et al.

Value

triad census with node attributes

Examples

library(igraph)
set.seed(112)
g <- sample_gnp(20, p = 0.3, directed = TRUE)
# add a vertex attribute
V(g)$type <- rep(1:2, each = 10)
triad_census_attr(g, "type")
