Random question generator

To get extra practice/experience with common problems, you can work with the random question generator. To use it, you must have R installed on your computer and be connected to the internet. You may then copy/paste:

source("http://myweb.uiowa.edu/pbreheny/misc/generator.R")

into R. You can then run any of the following commands.
