sp_network_nodes Class

An S4 class that contains all information on a single network. In this representation a network is composed of nodes which must be identified uniquely by and ID. Each node is described by variables stored in a data.frame. The node neighborhood matrix describes strength of links between the nodes of the network. The class is constructed by the sp_network_nodes() function.

# S4 method for sp_network_nodes

Arguments

object	A sp_network_nodes-class
value	An object to replace the existing id/data/neighborhood

Slots

network_id

A character that serves as an identifier for the network

nnodes

A numeric that indicates the number of nodes in the network

node_data

A data.frame that contains all information describing the nodes

node_neighborhood

A matrix that describes the neighborhood relations of the nodes
