knitr chunk in footnote with jekyll

问题

In the kramdown markdown documentation I read that I can insert multi line footnotes by indenting the next lines in the footnote. I tried to insert a knitr chunk into the footnote like this:

---
title: "test"
output: html_document
layout: post
---
My text[^1]

[^1]:This should appear in a footnote:
    ```{r}
    runif(1:10)
    ```

This worked when compiling the footnote directly with knitr:

If I let jekyll compile it it looks differently:

The code chunk is not really in the footnote. It is above it. And it is indented like this is not properly recognized as footnote annotation.

In config.yaml I defined markdown: kramdown.

回答1:

Knitr uses pandoc under the hood. To achieve the same output with Jekyll, you should use jekyll-pandoc, thus in config.yaml instead of markdown: kramdown then markdown: pandoc.

回答2:

As @mb21 pointed out switching markdown: kramdown to pandoc makes jekyll use the same markdown compiler as knitr does by default. You have to install the jekyll-pandoc gem first. This is best done with bundler:

According to bundler.io, in a command line:

gem install bundler
cd /path/to/my/project
bundle init

According to jekyll-pandoc:

nano Gemfile

overwrite with the following:

source "https://rubygems.org"

gem "jekyll-pandoc"

save.

Then:

bundle install

This will install jekyll-pandoc and all dependencies.

In your project add this to your _config.yaml:

# Build settings
gems:
  - jekyll-pandoc
markdown: pandoc

(replace markdown: kramdown).

To generate your site use this command inside R:

servr::jekyll(command="bundle exec jekyll build")
