Function to calculate T_bar.
tbar(partition, structure_matrix)
two-dimensinal matrix
of mode numeric
with
rows as types, columns as subcommunities, and elements containing relative
abundances of types in subcommunities. In the case of phylogenetic
metacommunities, these are the relative abundances of terminal taxa.
output$structure
of phy_struct()
; each
row denotes historic species, columns denote terminal taxa, and elements
contain branch lengths.
