Doing MDS (multi-dimensional scaling) and PCoA (principal coordinate analysis) is pretty easy with the cmdscale() option. However, there are some tricks to it and I show you how to create a distance matrix using a non-standard distance metric. If you want the code that I used in this video, you can get it from the StatQuest GitHub: https://github.com/StatQuest/mds_and_pcoa_demo/blob/master/mds_and_pcoa_demo.R For a complete index of all the StatQuest videos, check out: https://statquest.org/video-index/ If you'd like to support StatQuest, please consider...
