get_min_eccentricity {DiagrammeR} | R Documentation

## 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
    get_min_eccentricity(graph)
    #> [1] 2

    # Create a full graph and then
    # get the minimum eccentricity
    # value for that
    create_graph() %>%
      add_full_graph(n = 10) %>%
      get_min_eccentricity()
    #> [1] 1
