Chapter 6 Now over to you

You have seen few basic operations you can do in R. Now its time to try some yourself. These should be easy-peasy

6.1 Exercise 1

• Calculate th product of 155*12
• Store the result in the ‘results’ object (check that it now appears in your environment)
• Now take a squareroot of the results
• Save the results in the object ‘final_results’

6.2 Exercise 2

• Go back to the revenues example
• Assuming that our book did not sell that great after all and we only sold 50 copies.
• Our publisher did not like it so they decrease the royalties that we get from sales so publsiher can cover the cost of book production (new royalty is £3)
• What is the total revenue now?
