I’ve spent the month of April blogging my way through the tidyverse, while using my reading dataset from 2019 as the example. Today, I thought I’d bring many of those analyses and data manipulation techniques together to do a post about my reading habits for the year.**Deeply Trivial**, and kindly contributed to R-bloggers].
