R Markdown All-in-One for VS Code

NOTE: This extension has only been tested on Mac. It has been reported to fail on Windows/Linux

This extension provides a few snippets and key bindings for common tasks in .Rmd documents, such as inserting code chunks and including images using knitr::include_graphics().

Additionally, it aims to provide some helper functions for Bookdown and Blogdown.

This project is at its very early stage of development. Contributions are welcome!

Video Demos

If you prefer reading text, jump to RMarkdown-Specific Features, Blogdown-Specific Features, Bookdown-Specific Features, or Other Markdown Features.

Code Chunk

As you would do in RStudio, you can use Ctrl/Cmd+Alt+I to insert a code chunk (alternatively, you can write \code to trigger this snippet). The language defaults to R, but you can also use many other langauges supported by knitr.

The first tab stop allows you to configure this code chunk (language, label, eval, echo, etc.), and the second one is where you write the code. The third tab stop inserts a blank line between after the code chunk, which is required by the .Rmd format.

Include Graphics

In the world of R Markdown, knitr::include_graphics() is the preferred way of inserting images over Markdown's native ![]() syntax. If you don't know it, you should. Its syntax, however, is rather verbose.

With VSCode RMarkdown extension, you use the \fig snippet.

Knitting

Use Ctrl/Cmd+Shift+K to knit the document with options specified in the YAML header, like in RStudio.

RMarkdown-Specific Features

Keyboard Shortcuts:

Snippets

Cross-referencing

\ref or \@ref: general cross-reference; inserts \@ref($1) \refsec or \@sec: section cross-reference; inserts Section \@ref($1) \reffig or \@fig: figure cross-reference; inserts Figure \@ref(fig:$1) \reftab or \@tab: table cross-reference; inserts Table \@ref(tab:$1)

Chunks

\code: insert a code chunk \fig: insert a chunk using knitr::include_graphics() to include an image; hit tabs to conviniently fill out label, fig.cap and out.width.

Bookdown-Specific Features

Before you can use blogdown-specific features, you need to first open the directory of your bookdown project. The easiest way is to use RStudio's 'New Project'.

Serve Book

1. In the command palette (Ctrl/Cmd+Shift+P), search for serve book
2. Execute Blogdown: Serve Site
3. Click the link in the output to view your book
4. ~~You are redirected to your new site (not implemented yet)!~~

Blogdown-Specific Features

Before you can use blogdown-specific features, you need to first open the directory of your blogdown project. The easiest way is to use RStudio's 'New Project'.

New Post

1. In the command palette (Ctrl/Cmd+Shift+P), search for new post
2. Execute Blogdown: New Post, then fill out basic information (title, author, category, archetype)
   • You can set the default author in the settings Ctrl/Cmd + ,
3. You are redirected to your new post!

Serve Site

1. In the command palette (Ctrl/Cmd+Shift+P), search for serve site
2. Execute Blogdown: Serve Site
3. Click the link in the output to view your blog
4. ~~You are redirected to your new site (not implemented yet)!~~
