New exercises

We shall go through the course one more time by discussing a number of new exercises that will resemble in style those that will be presented at the final exam. We have been doing a lot of R programming throughout this spring  term. It's not so easy to allow this to enter a traditional school exam, but you will be asked to outline  informal programs where the syntax details do not count, and although such questions are not included in the Exercises E1-5 on April 30, they will be in later exercises in May.
