1.	__________ function is used in applying a function each level of factors.(a) With()(b) By()(c) To()(d) Here()I had been asked this question during an interview.I would like to ask this question from Functions in division Control Structures, Functions, Scoping Rules, Loop Functions and Debugging of R Programming
Answer» CORRECT answer is (B) By() For EXPLANATION: BY () function is used for applying a function each level of factors. R has a large number of in-built functions and also USER can create their own functions. In R, a function is an object. So the R interpreter is able to pass control to the function.
