[GitHub] [arrow] edponce commented on pull request #10196: ARROW-12575: [R] Use unary negative kernel

   The multiple negations and parenthesis are resolved on R side as only the resolved value is passed to the C++ backend. If the expression was passed as a string then it would make sense to check these cases.
   
   When we did the C++ tests, we checked for nested negations and they passed (although these tests were not included in the final PR).
