Setting order
If you want to change the order of your facets, it's best to properly define your factor variables before plotting.
Let's see this in action with the mtcars
transmission variable am
. In this case, 0
= "automatic" and 1
= "manual".
Here, we'll make am
a factor variable and relabel the numbers to proper names. The default order is alphabetical. To rearrange them we'll call fct_rev()
from the forcats
package to reverse the order.
