Description from the creator

In this screencast tutorial, Pat Schloss shows how you can use the separate function from the tidyverse's tidyr package to split a column of character data into new columns. In this episode, Pat will use separate along with pivot_longer and pivot_wider to create new columns representing each taxonomic rank for each genome in our dataset. 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.

The accompanying blog post contains the exercises and solutions can be found at riffomonas.org/code_club/2020-09-24-splitting-d….
