I'm still getting a large number of warnings when checking this, including:

1. Directly when installing, I get

Error in get(genname, envir = envir) : object 'testthat_print' not found

2. When checking, there is various

\examples lines wider than 100 characters:

Is this really running through for you when you use RStudio check?

@florianhartig I naively thought it might be a good idea to just add them and fix existing bugs in the GitAction branch, and did not reallise that redCards datasets contained massive non-ASCII character.
Anyway, I am currently trying to fix this and will create a PR then.
