In Statistical Program R

Part 1: Create a vectorized function that takes the last name and the sex ("M"/"F") of a customer and returns a customized greeting. To that aim, create a new variable `salutation` that has values `Mr.` or `Ms.` based on the participant sex in your function. Then return a greeting text that contains the salutation and the name.

Part 2: Then apply your greeting function to the variables in customers data frame below:

names <- c("Smith", "Miller", "Jones", "Brown", "Moore", "Jackson")

sex <- c("F", "M", "M", "F", "F", "M")

customers <- data.frame(names, sex)
