In this part of the book, you\'ll learn about data wrangling, the art of getting your data into R in a useful form for visualisation and modelling.
Data wrangling is very important: without it you can\'t work with your own data!
Wrangle encompasses three parts of the data science flow: importing, tidying, and transforming.
