Based on some of the feedback we've gotten on the reading quizzes we are going to have another extra R review session Tuesday night from 7PM-8:30PM (place TBD). I will just be going (very slowly) over the code we've already been through. If there are any special requests (concepts you don't understand, things you want to try etc.) send me an email by tomorrow night and I will try to put together some code addressing that topic. Be sure to come armed with questions!
