Creating multipart figures with facets: ggplot2's facet_wrap and facet_grid (CC039)

In this screencast tutorial, Pat Schloss shows how you can use ggplot's facet_wrap and facet_grid functions to make multipanel figures when you need to compare results across categorical variables. This episode is part of a larger arc of episodes investigating the sensitivity and specificity of amplicon sequence variants (ASVs), also known as exact sequence variants (ESVs). ASVs are growing in popularity for analyzing microbial communities using 16S rRNA gene sequences. Pat demonstrates these concepts by live coding at the command line interface using RStudio, GitHub Flow, and make.
