Introduction to the CPR package and Programmatic Construction of Calls

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
https://cran.r-project.org/package=cpr
or
https://github.com/dewittpe/cpr/

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

• match.fun()

• 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.
