Welcome to the Nvim-R wiki!

This is a markdown version of the official documentation. I have tried to hyperlink all references to sections within the documentation. Any that are still enclosed in pipes (eg: see |packages| for details) refer to the vim help and can be accessed from vim (:h packages). If there are any Nvim-R documentation links that have not been set or are broken, please open an issue in this repo.

Authors

Version: 0.9.19

For Neovim >= 0.6.0 and Vim >= 8.2.84

Overview

This plugin improves the support for editing R code with both Vim and Neovim, integrating them with R. Stable versions of this plugin are available available under Releases.

Feedback is welcomed. Please submit bug reports to the developers. Do not like a feature? Tell us and we may add an option to disable it.

The plugin should emit useful warnings if you do things it was not programmed to deal with. Cryptic error message are bugs. Please open an issue if you find errors.

Patches and git pull requests are welcome. If you want a feature that only few people might be interested in, you can write a script to be sourced by Nvim-R (see R_source).
