Degree.list: Degree (In-degree and Out-degree) of nodes

In shp2graph: Convert a SpatialLinesDataFrame Object to an 'igraph'-Class Object

Description

A function that returns degrees of nodes from provided “nodelist” and “edgelist”; while in-degrees and out-degrees are returned if edges are directed).

Usage

Degree.list(nodelist, edgelist, Directed=F)

Arguments

nodelist	A “nodelist” object
edgelist	An “edgelist” object
Directed	TRUE if edges are directed; FALSE, otherwise

Value

Lists of different contents are returned for undirected and directed edges respectively: For undirected graph:

DegreeL

An integer vector of degrees for each node in the given “nodelist”

For directed type:

InDegreeL	An integer vector of In-degrees for each node in the given “nodelist”
OutDegreeL	An integer vector of Out-degrees for each node in the given “nodelist”

Note

This function returns differently for undirected and directed networks, where both In-degrees and Out-degrees are calculated for a directed network, and only degrees are returned for an undirected networks.
