Converts an object into class phylo into class phy_struct.

phy_struct(tree, partition)

## Arguments

tree

object of class phylo

partition

two-dimensional matrix of mode numeric with rows as types (species), columns as subcommunities, and each element containing the relative abundance of types in each subcommunity relative to the metacommunity as a whole. In the phylogenetic case, this corresponds to the proportional abundance of historical species, which is calculated from the proportional abundance of terminal taxa

## Value

phy_struct() returns a list containing:

 $structure - each row denotes historical species, columns denote terminal taxa, and elements contain 'branch lengths' $tbar - the average distance from root to tip for all terminal taxa $parameters - information associated with each historical species $tree - object of class phylo
