...test? 😄

I was a bit hesitant on this one. We already have argument tests for this language. The problem only occurred when you had three or more arguments. I could of course add that test, but right now we have test parity between the languages due to the scope facets. If I add an argument test with three arguments here should I do it for all languages? Or maybe I should just add it here because the Tree sitter looks a bit different from other languages? Should that be a special facet for this and may be other languages? To be honest I'm not sure so I went with the old "When in doubt: do nothing" :D

Hmm good question. Simplest is just to add another test for R with 3 args using the actualArg facet. I think there's always going to be some variation between languages. Alternatively, you could add a new facet called actualArg.multiple or something like that, and then add it for all languages. But sorta goes combinatoric because you'd prob want that for parameters, etc. But I think one test that introduces slight variation between languages is better than nothing. I think "When in doubt, write a test" is probably a better mantra? 😅

Sounds reasonable :)
