The OpenCPU system exposes an http API for embedded scientific computing with R. The server can run either as a single-user development server within the interactive R session, or as a multi-user linux stack based on rApache and NGINX. The current R package implements the core of the system. When loaded in R, it automatically initiates the single-user server and displays the web address in the console. The OpenCPU website has more detailed API documentation.
