Here is the script file that we'll go over on Tuesday. I took what we had left from Lecture 3 and copied it over, so we'll just start from this one. We'll talk about how to deal with NAs in your data, and start looking at some more advanced data summaries.
Remember that Assignment 1 is due this Tuesday (2 days from now). You can just email it to me to turn in (sorry if I made you print it out already!). I should have another assignment with subsetting practice to post before class.
