github_document: Convert to GitHub Flavored Markdown

Description

Format for converting from R Markdown to GitHub Flavored Markdown.

Usage

github_document(
  toc = FALSE,
  toc_depth = 3,
  number_sections = FALSE,
  math_method = "default",
  preserve_yaml = FALSE,
  fig_width = 7,
  fig_height = 5,
  dev = "png",
  df_print = "default",
  includes = NULL,
  md_extensions = NULL,
  hard_line_breaks = TRUE,
  pandoc_args = NULL,
  html_preview = TRUE,
  keep_html = FALSE
)

Value

R Markdown output format to pass to render()

Arguments

toc

TRUE to include a table of contents in the output

toc_depth

Depth of headers to include in table of contents

number_sections

TRUE to number section headings

math_method

"default" means that native Github support for math notations using Mathjax syntax will be used. Other possible value is "webtex" where equation will be rendered to an image in the resulting Markdown. See html_document() for option to change webtex URL. Set math_methodto NULL to opt-out any math treatment.

preserve_yaml

Preserve YAML front matter in final document.

fig_width

Default width (in inches) for figures

fig_height

Default height (in inches) for figures

dev

Graphics device to use for figure output (defaults to png)

df_print

Method to be used for printing data frames. Valid values include "default", "kable", "tibble", and "paged". The "default" method uses a corresponding S3 method of print, typically print.data.frame. The "kable" method uses the knitr::kable function. The "tibble" method uses the tibble package to print a summary of the data frame. The "paged" method creates a paginated HTML table (note that this method is only valid for formats that produce HTML). In addition to the named methods you can also pass an arbitrary function to be used for printing data frames. You can disable the df_print behavior entirely by setting the option rmarkdown.df_print to FALSE. See Data frame printing section in bookdown book for examples.

includes

Named list of additional content to include within the document (typically created using the includes function).

md_extensions

Markdown extensions to be added or removed from the default definition of R Markdown. See the rmarkdown_format for additional details.

hard_line_breaks

TRUE to generate markdown that uses a simple newline to represent a line break (as opposed to two-spaces and a newline).

pandoc_args

Additional command line options to pass to pandoc

html_preview

TRUE to also generate an HTML file for the purpose of locally previewing what the document will look like on GitHub.

keep_html

TRUE to keep the preview HTML file in the working directory. Default is FALSE.

About Math support

Default behavior is to keep any inline equation using $ and any block equation using $$ in the resulting markdown as Github will process those using Mathjax. This feature is only available with Pandoc 2.10.1 and above

When using "webtex", PNG images with a white background are used by default so that it shows correctly on Github on both light and dark theme. You can choose to only output SVG for better quality by changing the URL used:

output:
  github_document:
    math_method:
      engine: webtex
      url: https://latex.codecogs.com/svg.image?

Background or fonts color cannot be changed for now and your equation may not be visible on dark theme.

Using "webtex" will be the default with Pandoc 2.0.4 until Pandoc 2.10. Before 2.0.4, Github document output does not support math.
