gl.tree.nj {dartR} | R Documentation |
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.
