Biplot with plot_ordination using PCoA and Bray distance #1717

Open microtonio opened 5 months ago

microtonio commented 5 months ago

Hello, I made this ordination plot using the PCoA method and the Bray distance. The plot_ordination function allowed me to create a biplot (samples on the left and taxa on the right). However, I thought that it was impossible to plot taxa with PCoA and bray distance as parameters because taxa (ASVs) are not part of the ordination in this case (as said in the ordination plots tutorial). The question is: how is it possible that I am able to plot the taxa on this graph? Is this graph correct? Can I associate the cluster of light blue samples on the right with the taxa on the right?
