"Variables with usage in Rd file ... but not in code" using roxygen2

[sbgraves237]

I'm getting:

Warning: Variables with usage in Rd file 'MaddisonCountries.Rd' but not in code: ‘MaddisonCountries’

in GitHub action on 5 platforms at:

https://github.com/sbgraves237/SS4Maddison

What am I missing?

Thanks, Spencer Graves

p.s. This is my first major effort to use "roxygen2". I'm trying to follow the instructions in your R Packages. I've so far been unable to understand this issue from studying this book and searching the net. I've found several entries on stackoverflow, but the suggestions I've found seem to use obsolete versions of roxygen2. I posted this question to StackOverflow 23 hours age:

https://stackoverflow.com/questions/79767947/variables-with-usage-in-rd-file-but-not-in-code-using-roxygen2

It has been "viewed 52 times" since then with no one offering a suggestion. Thanks for your valuable work.
