Create a vector in R that contains both numeric and logical elements. Check
the structure of the vector using the str() function. What is the data type of the
vector? What kind of coercion does it occur? Compute the sum and the mean of the
vector. Explain how R. deals with the logical elements when you compute the sum and
the mean. Attach R code.
