In this task sheet you will learn how to add new columns to a dataset with the mutate function. This lesson will also introduce the pipe operator, %>%, which allows you to chain together functions by “piping” the output of one function to the input of the next function. You will continue to work with the usdata dataset used in the task sheet GISTP 0025 - Filtering and Selecting Data with dplyr, which covers installing both dplyr and the usdata package.
