Taking a peek at your data

You can have a look at the first or last few entries (rows) of your data frame with the commands head() and tail(), respectively.

Note that you could also look at all of the data frame at once by typing its name into the console. However, since cdc has 20,000 rows, this would mean flooding the console screen. It's better to take small peeks at the data with head(), tail() or the subsetting techniques that you'll learn in a moment.

Instructions
