Custom aggregation level

The apply.*() functions from xts make for convenient aggregation, and are often the best choice functions to use, but sometimes you might want more control over the level of aggregation in your data.

In this exercise, you'll cover creating a custom level of aggregation of hourly_temperature using xts.

hourly_temperature, xts, and ggplot2 are loaded for you.
