Vim-R is a Vim plugin that transforms Vim into a full-featured integrated development environment for the R language. It provides interactive R console integration (via built-in terminal or external tmux), omni-completion for R objects and function arguments, an object browser, PDF preview with SyncTeX forward/backward search, and support for R Markdown, Rnoweb, and Quarto documents. The plugin communicates with R through a custom TCP/IP server (vimrserver) written in C and a companion R package (vimcom). While the plugin is superseded by R.nvim for Neovim users, the codebase demonstrates high craftsmanship in its multi-language architecture (VimL, C, R, Python) and remains functional for Vim users. It is not a data analysis tool but an editor enhancement for R development.
