I have processed my data through QIIME2 and have obtained my beta diversity distance matrices (DM) and PCoA plots (unifrac). I would like to customize my PCoA plot in R, but I am lost beyond importing my DM into R studio.
Any recommendations for a guide or specific code since I am a novice (at best) with R? My lab mainly uses SAS, but R produces better PCoA plots in my opinion.
I am using R Studio with R version 3.5.1.
