• From Week 3 onward, all homework must be done using R. • Attend the weekly TA tutorials, which will cover both R and data analytics. These tutorials are recommended for all students. • Take a special evening R test in week 10. The test is open book, open computer. • Submit all code for your final project as a loadable R workspace.
