PI2newick: Import data files from Phylogenetic Independance Package

Description

This function ensures to transform a data set written for the Phylogenetic Independance package of Abouheif (1999) in a data set formatting for the functions of ade4.

Usage

PI2newick(x)

Arguments

x

is a data frame that contains information on phylogeny topology and trait values

Value

Returns a list containing :

tre

: a character string giving the phylogenetic tree in Newick format

trait

: a vector containing values of the trait
