How do I graph on custom plots in ggplot2? : <p>I am using a plot obtained from the following site:
<a href="https://github.com/statsbylopez/blogposts/blob/master/fball_field.R" rel="nofollow noreferrer">https://github.com/statsbylopez/blogposts/blob/master/fball_field.R</a>
I do not know how to plot points on this. How would I go about doing this?</p>
