Class –

Because of the problems that have been found using version R 1.7.1, we are going to extend the deadline for the exam until Monday midnight. If you have already submitted a final exam and you want to take more time, please let me know immediately, before I grade what you have already submitted. If you had no problems with your code; if your final code produced no errors, then please be assured that there is nothing wrong with your work.

If on the other hand, you have been working off of my homework keys and continue getting strange errors, these may be resulting from the version of R you are using. To update your version, go back to the folder on the course website “Put R on your computer” and following the instructions there, install version 1.8.1, which I have put on the website.

Let me know if you have any problems or concerns,

Jacob
