Given a phylo object, and a picante-style community data matrix (sites are rows, species are columns), prepare data for analysis.
prepData(tree, picante.cdm, optional.dists = NULL)Phylo object.
A picante-style community data matrix with sites as rows, and species as columns
A symmetric distance matrix can be directly supplied. This option is experimental. Behavior depends on metric being used. If the metric in question relies on the phylogenetic distance matrix from a call to cophenetic(tree), then this optional distance matrix will be inserted instead.
An object of class metrics.input
Returns a named list with three elements: the original phylogenetic tree phylogenetic distances among species, and the original picante-style CDM.
