lozupone_tree {abdiv}

Example data for UniFrac distance

Description

This example was used to illustrate unweighted UniFrac distance in Lozupone and Knight (2005).

Usage

lozupone_tree

lozupone_panel_a

lozupone_panel_b

Format

lozupone_tree is a phylogenetic tree with 14 tips, labeled A-N. It was created with the ape library.

The data frames lozupone_panel_a and lozupone_panel_b are transcribed from Figure 1 of the paper. They have the following columns:

Species

The species label, matching to the phylogenetic tree.

SampleID

The community, either "Circle" or "Square".

Counts

The number of organisms counted per species, always 1 for this example.
