Please answer in R programming language:
Q2. Below is an R function that takes a numeric vector as an argument and returns the difference between the largest and smallest item in the vector x. (15 points: 5+10] DiffMaxMin <- function(x){ return(max(x)-min(x)) } Now use map functionality and the above DiffMaxMin function to get the difference between the largest and smallest item in each column of a numeric data frame df given below. Note that the purpose of map functions is to avoid using loops. df <- data.framel a = rnorm(10), b = rnorm(10), C= rnorm(10), d = rnorm(10) ) • Perform the above task by using for-loop and without using map or lapply functionalities.
