Alternatives to ordination in R: Visualizing community change relative to a specific point (CC207)
Channel: Riffomonas Project
Date: 2022-04-25

An ordination has a limited set of uses. But are there alternatives to ordination for displaying beta-diversity data? In this episode, Pat shares one method for showing differences between groups of observations using a jittered plot with summary statistics overlayed on the points. He'll demonstrate this approach by using functions from vegan, dplyr, and ggplot2.

You can find my blog post for this episode at https://www.riffomonas.org/code_club/2022-04-25-jitter-distance-plot. The data were generated in our Kozich et al. 2013 paper (http://doi.org/10.1128/AEM.01043-13) using samples from the Schloss et al. 2012 paper (http://doi.org/10.4161/gmic.21008).
