Chapter 10 irtools

The irtools package is one of the key packages in the irverse suite of packages. This package provides a good deal of helper functions and definitions that support a lot of the analytic procedures performed in the Office of Institutional Research. It is strongly advised to become familiar with this package. Additionally, this package should grow to include more and more helper functions that become salient in the office. As with packages, anything you do more than once should become a function. If you use a function several times you should roll it into a package.
