Projects

I use R for statistical computing. Check out some of my projects here.

I use Github for version control and collaboration. My package bouldr (still a work in progress) makes it easy to do Receiver Operator Characteristic Curve analyses and plot the results.

I use OSF.io for collaboration and dissemination. I have a bunch of projects there, including posters, papers, and talks.

The latest version of the Reactive Aggression Assessment (RAGA-16) is available on OSF here.
