1.2 How it works

API for calling R functions and scripts, and managing resources (objects, files, graphics, …)
Central: leverages R packages. Packages are natural and powerful container format for R bundling and shipping R code, data, manuals and files.
Apps in OpencPU are simply R packages containing R functions.

Very flexible and scalable R backend. Builds apps, call it from services or data pipelines.
