Do the coding in R langauge and answers the following questions.

Exercise 3.3 Create and store a three-dimensional array with six layers of a 4 2 matrix, filled with a decreasing sequence of values between 4.8 and 0.1 of the appropriate length. Extract and store as a new object the fourth-and first-row ele- ments, in that order, of the second column only of all layers of (a) Use a fourfold repetition of the second row of the matrix formed in (b) to fill a new array of dimensions 2 2 2 3. Create a new array comprised of the results of deleting the sixth layer of (a) Overwrite the second and fourth row elements of the second column of layers 1, 3, and 5 of (d) with -99. a. b. c. d. e.
