Vim bekapcsolása R IDE-be

Hogyan lehet Vim-et IDE-vé alakítani R

Figyelem : Nem , ez nem az R beállítás, amelyet kezdőnek kell használni. Az RStudio IDE csodálatos, és valószínűleg mindig az alapértelmezett eszköznek kell lennie. Azonban, ha véletlenül a Vim / Emacs föld kitaszított birodalmához tartozol, akkor ez a bejegyzés neked szólhat. Emellett megemlítem Vim-et és Neovim-t a bejegyzés során, ezen a ponton nagyrészt egyformák. Tehát, ha az egyikhez vagy a másikhoz kötődik, nem számít.

Miért nem csak az RStudio-t használja?

Valóban nagy kérdés. Számomra a fő ok a gyorsaság és az ismertség. Igen, tudom, hogy az RStudio rendelkezik Vim billentyűzárral, de ez nem az igazi . Ezen a ponton Vim tönkretesz. Egy magányos őrült erőteljesen ütsc>; and in Microsoft Word only to be disappointed.

However, all is not lost.

R In Vim

At first, the pursuit of R in Vim seems like an exercise in brutalism. You’re options are few and support seems bleak.

Your best option will be to utilize a separate :terminal buffer. The basic workflow goes as follows:

  • Write code in myFile.R
  • Visually select code
  • Paste code in :terminal buffer
  • Execute code
  • Rinse and repeat

This may not seem too bad, however it gets tedious fairly quickly. Plus, this approach leaves a lot to be desired. Mainly, viewing what’s defined, perusing the data, and some basic completion + linting.

Nvim-R To The Rescue

Nvim-R is easily one of my favorite plugins for Vim. It takes an old water pistol and transforms it into a fully functioning machine gun. It comes stocked with many gems that will make you regret you haven’t been using it all along. So, enough with the poetic waxing. Let’s jump into making Vim our new R home.

The first step to R enlightenment is…you guessed it, installing Nvim-R. I use Vim-Plug, so that’s what I show below. However, you can just as easily install it using whatever plugin manager you choose.

Plug 'jalvesaq/Nvim-R'

Now if you open an R file and hit \rf you’ll see a terminal buffer appear with an R console tied to your current session. To end it, hit \rq.

One important thing to note, the console is not tied to just the current buffer. This means that you can have multiple buffers all feeding into the same console. This can be good / bad depending on your personal preferences. I enjoy it, but it can definitely throw you for a loop if you’re careless. For a deeper dive on how R and Vim communicate in Nvim-R you can head here.

Secret Sauce

Now that you’ve got the basics up and running we can dive into all that Nvim-R has to offer. There are a vast amount of built-in shortcuts, for the full list you can read the documentation here. I will briefly cover a handful of useful commands that will serve you well on a daily basis.

Sending Lines

The most immediate need is to be able to send lines of code. There are a variety of ways to do so in Nvim-R:

  • Send :: Entire File \aa
  • Send :: Entire Block \bb
  • Send :: Entire Function \ff
  • Send :: Entire Selection \ss
  • Send :: Entire Line \l

As you can begin to see the forward slash \ is the leader for many operations. However, most of these, and the minor distinctions between them, are superfluous. You will likely be better served by remapping a few of them.

" in your .vimrc /init.vim
“ remapping the basic :: send linenmap , RDSendLine
“ remapping selection :: send multiple linesvmap , RDSendSelection
“ remapping selection :: send multiple lines + echo linesvmap ,e RESendSelection

I chose to remap the basic send line + multiple lines to my comma key. This significantly cuts down on the number of keys I have to utilize. Furthermore, the ,e mapping allows me to check that the lines I sent were computed correctly. For the most part, these three mappings will allow you to do everything you need to. There are a few more worth mentioning though, and may add something to your workflow if remapped.

Object Browser

First up, the object browser. This feature, solicited by typing \ro will allow you to see what variables and libraries are active in your current environment.

Objects can also be viewed by typing \rl, which will run the ls() function in your current console.


In order to get a better understanding of your code you have a couple options. From within Nvim-R there are two of particular note \rh — help and \re — example. Each of these will open in a split buffer with the relevant information.

Another worthwhile option is the Dash plugin. The easiest path to usage is as follows:

“ install plugin :: using vim-plugPlug ‘rizzatti/dash.vim’
“ remap search keynmap  d DashSearch

Now, when you are seeking more information on a piece of R code, or any other language, all you have to do is place your key over the word and hit r>d. The Dash app will then pop up with the relevant information. You can also search Google and Stack Overflow from within it. It’s a great tool, especially for Vimmers who utilize Vim for a variety of languages.

Viewing Data

Next up is getting a quick peak at your data. RStudio comes with a beautiful built in data viewer, which can be handy for getting a sense of the data. In Vim, it’s a little harder, but not impossible.

Nvim-R allows you to view a data frame by using the \rv command. This will either show the data frame using X Quartz, on Mac, or the CSV plugin for Vim, if you have it installed.

The CSV plugin comes with a whole host of additional features for manipulating data, but that is outside of the scope of this article. By and large, my suggestion would be to use Excel. While overly beloved by many, it does serve as a good data viewer.

Other Tips & Tricks

Despite what you may think, there is still more, and even more that I won’t cover. But, these next few tricks are definitely worth keeping in mind.

Inline Code Output

If you have a line of code and hit \o you’ll see the output rendered as comments in your current file.


Instead of doing the basic flow of str() + plot(), etc…Nvim-R allows for a simplified flow.

  • summary() :: \rs
  • plot() :: \rg
  • args() :: \ra
  • setwd() :: \rd
  • print() :: \rp
  • names() :: \rn


Arrows can be a pain to type. Luckily, Nvim-R makes it easier by mapping _ to <-. This may, or may not, completely bewilder you. If you’re someone who prefers snake case, then you’ll have to hit the underscore twice in order to get an actual underscore, and not an arrow. However, you can override this setting. I find it useful, and have adjusted, but can certainly understand others being irked.


Often I see lack of code completion as a major reason people skip Vim. This notion is incorrect though. Code completion is very much apart of Vim. For our specific purpose, namely completion for R, there are, yet again, a few options.

Nvim-R Completion

Nvim-R supports code completion out of the box. You will have to manually engage it by using ; for an object name, or for a function argument. For some people this workflow is ideal, but in the current age of VS Code’s Intellisense, and other such options, this feels clunky.


Ncm-R is your best bet for as-you-type sort of completions. It’s a fairly new package, but a much welcomed addition. It integrates with Nvim-R to provide asynchronous completions for R via nvim-completion-manager.

Ncm-R provides rich completions for all of the following:

  • Objects from the global R environment
  • Functions from all loaded packages
  • Packages inside library() and require()
  • Datasets inside data()
  • Arguments inside functions
  • Variables inside pipes %>% and ggplots +

For a basic set up add the code below to your Vim configuration file.

Plug ‘roxma/nvim-completion-manager’Plug ‘gaalcaras/ncm-R’
“ Optional: for snippet supportPlug ‘sirver/UltiSnips’

R Language Server

If you are unfamiliar with what a language server is head here. If you are familiar, then this project may be of interest. It is still in the early days, and largely experimental, but does work and currently supports both code completion and linting.


Last but not least, linting. The set up for quality linting is fairly straightforward. You’ll want to use ALE, Asynchronous Lint Engine, as your driver. You can set this up in your .vimrc as follows:

Plug ‘w0rp/ale’

Now all you need to do is install lintr. This can be done by using install.packages(‘lintr’).

Now, the next time you open up an .R file you should be good to go.


At this point, you have a killer set up for R in Vim. There is certainly more to do though if you’re curious. Areas for further exploration include looking through all of the documentation in the plugins I have linked throughout this article. You’ll find many helpful tips and tricks in there, as well as useful settings. I hope this helped to get you up and running with R in Vim!
