Peter DeWitt will be presenting two topics.

First, the cpr (control polygon reduction) R package will be introduced. The cpr package provides a set of tools for working with uni- and multi-variable B-splines, and most importantly, efficiently finding parsimonious B-spline regression models with high quality of fit.

You can get the cpr package from

Discussion of the implementation of the CPR algorithm within the cpr package segues into the second topic, programmatic construction and evaluation of calls within R. This will highlight


* stats::update()

* formulas, and

* Environments.

Peter will start his talk around 7:30pm. We'll use the time between 7:00pm and 7:30pm to socialize and answer generic R questions. After the talk there is usually a small group who will head out for a beer and burger. Hope to see you at Galvanize.
