Rolling minimum
The zoo package has several rolling window functions for common summary statistics like mean, median, sum, etc. However, not all statistics have a rolling function, so an important skill is to be able to apply any given function to a rolling window!
In this exercise, you'll apply a function to a rolling window generated from the daily_temp time series.
