R is a programming language widely used by statisticians for data analysis. It's a popular language with excellent support within a Jupyter notebook environment.
In Gradient you'll find a 1-click runtime optimized for R in the All Runtimes view.
The runtime builds a container from the Docker Hub image located here.
Once the image builds, you'll see a very simple demo R notebook.
From here you can start working in R!
If you require a Jupyter notebook environment, you can swap over from the Gradient IDE easily.
