Network Radius — network_radius • cograph

Computes the radius of a network - the minimum eccentricity across all nodes. The eccentricity of a node is the maximum shortest path distance to any other node. The radius is the smallest such maximum distance.

Usage

network_radius(x, directed = NULL, ...)

Arguments

x: Network input: matrix, igraph, network, cograph_network, or tna object
directed: Logical or NULL. Consider edge direction? Default NULL, which follows the directedness of the converted graph.
...: Currently unused; directed is already an explicit argument above and to_igraph accepts no others.

Value

Numeric: the network radius

Examples

# Star graph: center has eccentricity 1, leaves have 2, so radius = 1
star <- matrix(c(0,1,1,1, 1,0,0,0, 1,0,0,0, 1,0,0,0), 4, 4)
network_radius(star)  # 1
#> [1] 1
