Hello, I was wondering if I could ask you an additional question? The page wont allow me to make another post.

Creating a calculated Average / Ratio to plot on a Geom_line comparing yearly data

Hello All, In some cases I use Tableau to show some visual work, but I would like to learn how to do that in R. What I would like to do is get a calculated average / ration of a positivity ratio seen like in the picture attached to this thread. below I have began a code and it will depict a visual showing total positive cases each month in the year of 2019 and 2020. Example: In January of 2019 there were 10 new cases. However, as mentioned, I would like that to be converted into a ratio shown over the year. Example: In the graph shared, there was a 0.53% Positivity ratio. I think I am just stuck on the calculation part and would appreciate all the help. Thank you so much! Aphirm_201…
