R anesrake error: “Error in x + weights: non-numeric argument for binary operator” Ask Question

Great! Please mark *your answer (no false modesty!) the solution for the benefit of those to follow.

Again, it's best to avoid naming objects data because that is also the name of a built-in function. You can check with
