get_min_eccentricity

Get the minimum graph eccentricity

Description

Get the radius of a graph, which is the smallest eccentricity in the graph. The graph eccentricity of a node is its shortest path from the farthest other node in the graph.

Usage

get_min_eccentricity(graph, direction = "all")

Arguments

`graph`	A graph object of class `dgr_graph`.
`direction`	Using `all` (the default), the search will ignore edge direction while traversing through the graph. With `out`, measurements of paths will be from a node whereas with `in`, measurements of paths will be to a node.

Value

A single numeric value representing the minimum eccentricity of the graph.

Examples

# Create a cycle graph
graph <-
  create_graph() %>%
  add_cycle(n = 5)

# Determine the graph's minimum
# eccentricity
graph %>%
  get_min_eccentricity()

# Create a full graph and then
# get the minimum eccentricity
# value for that
create_graph() %>%
  add_full_graph(n = 10) %>%
  get_min_eccentricity()
