newick2phylog: Create phylogeny

In ade4: Analysis of Ecological Data: Exploratory and Euclidean Methods in Environmental Sciences

Create phylogeny

Description

The first three functions ensure to create object of class phylog from either a character string in Newick format (newick2phylog) or an object of class 'hclust' (hclust2phylog) or a taxonomy (taxo2phylog). The function newick2phylog.addtools is an internal function called by newick2phylog, hclust2phylog and taxo2phylog when newick2phylog.addtools = TRUE. It adds some items in 'phylog' objects.

Usage

newick2phylog(x.tre, add.tools = TRUE, call = match.call())
hclust2phylog(hc, add.tools = TRUE)
taxo2phylog(taxo, add.tools = FALSE, root="Root", abbrev=TRUE)
newick2phylog.addtools(res, tol = 1e-07)

Arguments

x.tre	a character string corresponding to a phylogenetic tree in Newick format (http://evolution.genetics.washington.edu/phylip/newicktree.html)
add.tools	if TRUE, executes the function newick2phylog.addtools
call	call
hc	an object of class hclust
taxo	an object of class taxo
res	an object of class phylog (an internal argument of the function newick2phylog)
tol	used in case 3 of method as a tolerance threshold for null eigenvalues
root	a character string for the root of the tree
abbrev	logical : if TRUE levels are abbreviated by column and two characters are added before

Value

Return object of class phylog.
