R Coding Question

Please help by answering all the questions and their subparts. Thanks!

1. Write R code that asks you to input a positive integer n and then computes n! and writes it back out to the screen. You may not use the built-in function factorial(). Use good programming style. Run it a couple times and include the console runs in your hand-in. Use an R script file and hand in the R script. 2. Using a for-loop, write R code that computes the first 2000 terms of summing 1', that is, computes z where n=2000 Z = E n=1 What is this number z? 3. Using a while-loop that runs for 25 iterations, print to screen for each iteration of the loop what its iteration number is. Identify each exercise and sub exercise and include the answers (R outputs) to the file. Together with your R script of your code, also hand in a text file (ends in .txt) of the cleaned-up console run too
