Welcome to your interview.
The question is on your right: R Operators and ADxx Variables. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Can you tell me the name of an operator in R, and what are the name of the variables used for creating ADxx table?
