Exercise

Creating Date objects

The readr import functions can automatically recognize dates in standard ISO 8601 format (YYYY-MM-DD) and parse columns accordingly. If you want to import a dataset with dates in other formats, you can use parse_date().

In this exercise, you'll be working with some weather data. Each date is stored according to American convention: MM/DD/YYYY. In order to specify this format, you'll use %m for two-digit month, %d for two-digit day, and %Y for four-digit year.
