SoS Notebook is a Jupyter kernel that allows the use of multiple kernels in one Jupyter notebook. Although SoS Notebook can work with any kernels using magics %expand, %capture and %render, a language module allows the exchange of variables among supported languages using magics %get, %put, %use, and %with. This module provides a language module for the R programming language.
If you are using a conda environment,
conda install sos-r -c conda-forge
installs all required component of sos-r, including sos-notebook, R, irkernel, and required packages.
If you are not using a conda environment, or if you would like to use a standalone R installation (instead of conda's R), you should install sos-notebook, sos-r etc separately. Please refer to Running SoS for details.
After proper installation of sos-r, you should see language R in the language selection dropdown box of a SoS Notebook. Please refer to SoS Homepage and SoS Notebook Documentation for details.
