The factorial of a positive integer, n, denoted by n!, is the product of all positive integers less than or equal to n, i.e. n! = n x (n – 1) x ( n – 2) x (n – 3) x . . . . x 3 x 2 x 1. For example: 5! = 5 x (5 – 1) x ( 5 – 2) x (5 – 3) x (5 – 4) = 5 x 4 x 3 x 2 x 1 = 120 using a while loop control structure, write your own function called my.factorial to compute the factorial value for any given integer, n. Your code must: • be preceded by the pseudocode • only use the R base library (no external packages) • consist of appropriate control structure(s) • provide correctly defined function(s) • be fully commented • run without error
