All of the activities in this chapter will be conducted in a single R script. R scripts are files with the .R extension which are analogous to Python scripts. This chapter will make use of the RStudio IDE rather than a text editor for editing code, so you will be able to create this script from within RStudio (I will explain how to do this later in the chapter).

The R script containing the code for this chapter is called r_intro.R and is available in the code folder of the external resources. All external resources are available at the following link: https://goo.gl/8S58ra.
