WebMDS (“PCoA”) on Unifrac Distances. Use the ordinate function to simultaneously perform weightd UniFrac and then perform a Principal Coordinate Analysis on that distance matrix (first line). Next pass that data and the ordination results to plot_ordination to create the ggplot2 output graphic with default ggplot2 settings. Webr"""Perform Principal Coordinate Analysis. Principal Coordinate Analysis (PCoA) is a method similar. to Principal Components Analysis (PCA) with the difference that PCoA. operates on distance matrices, typically with non-euclidian and thus. ecologically meaningful distances like UniFrac in microbiome research.
