read_csv
CSV files can be imported with read_csv(). It's a wrapper function around read_delim() that handles all the details for you. For example, it will assume that the first row contains the column names.
The dataset you'll be working with here is potatoes.csv (view). It gives information on the impact of storage period and cooking on potatoes' flavor. It uses commas to delimit fields in a record, and contains column names in the first row. The file is available in your workspace. Remember that you can inspect your workspace with dir().
