General Data Wrangling and Analysis Resources
Because most material that discusses data wrangling and analysis with the dplyr packges does so in a way that covers all of the verbs discussed in this course, I have chosen not to separate them by lesson. Instead, here are some helpful resources for learning more about all of the tidyverse verbs discussed in this course:
Chapter 5 of R for Data Science
RStudio Cloud primer on working with data
Tidyverse for Beginners by Danielle Navarro
Learning Statistics with R by Danielle Navarro
Introduction to the Tidyverse by Alison Hill
