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. https://images.squarespace-cdn.com/content/v1/5eed0662fd73bd56931c4687/1592597985203-DW2CZHB3IW7OZ7T9E9OV/20191011_153733.jpg Josh Langfus's Page - About me I'm passionate about science, food, music, and service.
