1.1 Importing data

• We’ll use the Salaries dataset to illustrate that R can import data from many different sources.

• It is provided in other formats (i.e. .csv, .txt, .xsls) in Appendix A of the book so that you can practice importing data.

• The dataset describes the 9 month academic salaries of 397 college professors at a single institution in 2008-2009.
