max_closeness {treestats}

Maximum closeness

Description

Closeness is defined as 1 / Farness, where Farness is the sum of distances from a node to all the other nodes in the tree. Here, we return the node with maximum closeness.

Usage

max_closeness(phy, weight = TRUE, normalization = "none")

Arguments

phy

phylo object or ltable

weight

if TRUE, uses branch lengths.

normalization

"none" or "tips", in which case an arbitrary post-hoc correction is performed by dividing by the expectation of n log(n), where n is the number of tips.

Value

Maximum Closeness
