Outputs an nj tree to summarize genetic similarity among populations

Description

This function is a wrapper for the nj function or package ape applied to Euclidean distances calculated from the genlight object.

Usage

gl.tree.nj(
  x,
  d_mat = NULL,
  type = "phylogram",
  outgroup = NULL,
  labelsize = 0.7,
  treefile = NULL,
  verbose = NULL
)

Arguments

x	Name of the genlight object containing the SNP data [required].
d_mat	Distance matrix [default NULL].
type	Type of dendrogram "phylogram"|"cladogram"|"fan"|"unrooted" [default "phylogram"].
outgroup	Vector containing the population names that are the outgroups [default NULL].
labelsize	Size of the labels as a proportion of the graphics default [default 0.7].
treefile	Name of the file for the tree topology using Newick format [default NULL].
verbose	Specify the level of verbosity: 0, silent, fatal errors only; 1, flag function begin and end; 2, progress log; 3, progress and results summary; 5, full report [default 2].

Details

An euclidean distance matrix is calculated by default [d_mat = NULL]. Optionally the user can use as input for the tree any other distance matrix using this parameter, see for example the function gl.dist.pop.

Value

A tree file of class phylo.
