Indegree

This metric is implemented in every version.



The Indegree of a node is the number of its incoming edges.

Objective

The Indegree of a node d_{I} (n_i)\,\! considers the number of all nodes that terminate in n_i\,\! [1].

This measure is a specialized variant of Degree. It is also called Indegree-based Prestige.

Calculation

The Indegree is equal to the number of arcs l_k \langle n_j,n_i \rangle\,\! for all l_{k} \in L\,\! and n_i, n_j \in N\,\!, where N\,\! is a set of nodes and L\,\! a set of edges of a network.

Statement

R-example
library(igraph)
g <- graph.ring(10)
degree(g, mode = c("in"))
