Create a value box for the maximum velocity

Now you can begin building your dashboard! First, create a value box for the maximum velocity of a fireball at peak brightness (the variable vel in your nasa_fireball data frame). There are many ways to find the maximum value in R; be sure to remove NA values when doing so.

The nasa_fireball data frame has already been loaded.
