Showing groups on a scatter plot for an ordination using ggplot2 (CC079)

Showing groups in a scatter plot to indicate the region covered by points from different groups can help your audience understand whether you see structure in your data. In this episode of Code Club, I'll show a variety of approaches you can take to show which points belong to different groups in a scatter plot. We'll cover plotting a centroid, adding rays out from the centroid, ellipses, and a 2 dimensional density plot (whoa!). Pat will use RStudio and functions from the ggplot2 package and other packages from the tidyverse. The accompanying blog post can be found at https://www.riffomonas.org/code_club/....
