picante: Integrating Phylogenies and Ecology

Description

Functions for phylocom integration, community analyses, null-models, traits and evolution. Implements numerous ecophylogenetic approaches including measures of community phylogenetic and trait diversity, phylogenetic signal, estimation of trait values for unobserved taxa, null models for community and phylogeny randomizations, and utility functions for data input/output and phylogeny plotting. A full description of package functionality and methods are provided by Kembel et al. (2010) <doi:10.1093/bioinformatics/btq166>.

evol.distinct：Species’ evolutionary distinctiveness

介绍：Calculates evolutionary distinctiveness measures for a suite of species by: a) equal splits (Redding and Mooers 2006) b) fair proportions (Isaac et al., 2007). Returns a datafram with species identifiers and species scores.

Usage

evol.distinct(tree, type = c("equal.splits", "fair.proportion"), scale = FALSE, use.branch.lengths = TRUE)
