Chapter 5 Welcome to the Tidyverse

In this lesson we will be using a group of packages which are part of what is known as the tidyverse. These packages include :

  • readr for importing data into R
  • dplyr for handling common data wrangling tasks for tabular data
  • tidyr which enables you to swiftly convert between different data formats (long vs. wide) for plotting and analysis
  • lubridate for working with dates
  • ggplot2 for visualizing data.

For the full list of tidyverse packages and documentation visit You can install these packages individually, or you can install the entire tidyverse in one go.
