measure_properties {manynet}

Describing network properties

Description

These functions extract certain attributes from given network data:

• net_nodes() returns the total number of nodes (of any mode) in a network.

• net_ties() returns the number of ties in a network.

• net_dims() returns the dimensions of a network in a vector as long as the number of modes in the network.

• net_node_attributes() returns a vector of nodal attributes in a network.

• net_tie_attributes() returns a vector of tie attributes in a network.

These functions are also often used as helpers within other functions.

Usage

net_nodes(.data)

net_ties(.data)

net_dims(.data)

net_node_attributes(.data)

net_tie_attributes(.data)

Arguments

.data

An object of a manynet-consistent class:

• matrix (adjacency or incidence) from {base} R

• edgelist, a data frame from {base} R or tibble from {tibble}

• igraph, from the {igraph} package

• network, from the {network} package

• tbl_graph, from the {tidygraph} package

Value

⁠net_*()⁠ functions always relate to the overall graph or network, usually returning a scalar. net_dims() returns an integer of the number of nodes in a one-mode network, or two integers representing the number of nodes in each nodeset in the case of a two-mode network. ⁠net_*_attributes()⁠ returns a string vector with the names of all node or tie attributes in the network.
