Toward a grammar of psychological experiments
summary
An R package called xprmntr compiles R experiment code into jsPsych JavaScript, uses a thin plumber server for backend data, and deploys to GitHub Pages or Google App Engine. It writes trials that accept keyboard, button or slider responses, saves results as CSV, supports images/audio/video, and offers timeline logic with if and loop primitives. The system works for teaching and running hundreds of web experiments but remains janky and limited by many specialized jsPsych plugins.
