rOpenSci review: Coding style

[ahasverus]

The following point has been raised in the review:

I see that you have a "style guide" section in your Contributing.md file. That's great, but I wonder if it might make your life easier to use automated styling/formatting if you're not doing so already (via styler or air). I can see you have many contributors; automated styling/formatting will make it easier to works on a single codebase across many contributors.

We will use air on Positron IDE and change the "Style guide" section in the Contributing.md file to encourage future contributors to use the same formatter.
