## What it is
IRkernel is an R kernel for Jupyter that lets users run R code in Jupyter notebooks, consoles, and other Jupyter frontends. It registers R as a kernel via a CRAN-installable package and communicates with Jupyter over ZeroMQ.

## Use cases
- run R code in Jupyter notebooks
- use R with JupyterLab
- register multiple R versions as Jupyter kernels
- interactive R data analysis in notebooks
- use R in jupyter console or qtconsole
- set up R notebooks in Docker

## When to avoid
- you only need R scripting without notebooks
- you want a full R IDE experience like RStudio
- you work in a language other than R

## Facets
- artifact type: plugin
- maturity: stable
- function: sdk, developer-tools
- domain: data-science, developer-tools, programming-languages
- platform: cross-platform, python
- tags: jupyter-kernel, r-language, notebooks, repl, zmq, docker
