This course will examine two R packages: The Rcmdr ("R Commander") package, with provides an extensible basic-statistics graphical user interface (GUI) for R; and the sem package, which provides a latent-variable structural-equation modeling facility in R. I will describe the general design principles employed in developing these packages, and will discuss how to add to their capabilities. Each student, working either independently or collaboratively, will complete a project that augments one of the two packages. I assume that students have some familiarity with R programming.
