  fig_width = 8,
  fig_height = 6,
  fig_retina = 2,
  fig_caption = TRUE,
  dev = "png",
  df_print = "default",
  self_contained = TRUE,

)

Arguments

number_sections

TRUE to number section headings

incremental

TRUE to render slide bullets incrementally. Note that if you want to reverse the default incremental behavior for an individual bullet you can precede it with >. For example: > - Bullet Text

slide_level

The heading level which defines individual slides. By default this is the highest header level in the hierarchy that is followed immediately by content, and not another header, somewhere in the document. This default can be overridden by specifying an explicit slide_level.

duration

Duration (in minutes) of the slide deck. This value is used to add a countdown timer to the slide footer.

footer

Footer text (e.g. organization name and/or copyright)

font_adjustment

Increase or decrease the default font size (e.g. -1 or +1). You can also manually adjust the font size during the presentation using the 'S' (smaller) and 'B' (bigger) keys.

fig_width

Default width (in inches) for figures

fig_height

Default height (in inches) for figures

fig_retina

Scaling to perform for retina displays (defaults to 2, which currently works for all widely used retina displays). Set to NULL to prevent retina scaling. Note that this will always be NULL when keep_md is specified (this is because fig_retina relies on outputting HTML directly into the markdown document).

fig_caption

TRUE to render figures with captions

dev

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

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.

self_contained

Produce a standalone HTML file with no external dependencies, using data: URIs to incorporate the contents of linked scripts, stylesheets, images, and videos. Note that even for self contained documents MathJax is still loaded externally (this is necessary because of its size).

highlight

Syntax highlighting style. Supported styles include "default", "tango", "pygments", "kate", "monochrome", "espresso", "zenburn", and "haddock". Pass NULL to prevent syntax highlighting.

mathjax

Include mathjax. The "default" option uses an https URL from a MathJax CDN. The "local" option uses a local version of MathJax (which is copied into the output directory). You can pass an alternate URL or pass NULL to exclude MathJax entirely.

template

Pandoc template to use for rendering. Pass "default" to use the rmarkdown package default template; pass NULL to use pandoc's built-in template; pass a path to use a custom template that you've created. See the documentation on pandoc online documentation for details on creating custom templates.

css

One or more css files to include

includes

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

keep_md

Keep the markdown file generated by knitting.

lib_dir

Directory to copy dependent HTML libraries (e.g. jquery, bootstrap, etc.) into. By default this will be the name of the document with _files appended to it.

md_extensions

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

pandoc_args

Additional command line options to pass to pandoc

extra_dependencies

A LaTeX dependency latex_dependency(), a list of LaTeX dependencies, a character vector of LaTeX package names (e.g. c("framed", "hyperref")), or a named list of LaTeX package options with the names being package names (e.g. list(hyperef = c("unicode=true", "breaklinks=true"), lmodern = NULL)). It can be used to add custom LaTeX packages to the .tex header.

...

Additional function arguments to pass to the base R Markdown HTML output formatter html_document_base

Value

R Markdown output format to pass to render
