revealjs_presentation: Convert to a reveal.js presentation
In revealjs: R Markdown Format for 'reveal.js' Presentations

Description Usage Arguments Details Value Examples

Format for converting from R Markdown to a reveal.js presentation.

revealjs_presentation(incremental = FALSE, center = FALSE,
  slide_level = 2, fig_width = 8, fig_height = 6, fig_retina = if
  (!fig_caption) 2, fig_caption = FALSE, smart = TRUE,
  self_contained = TRUE, theme = "simple", transition = "default",
  background_transition = "default", reveal_options = NULL,
  reveal_plugins = NULL, highlight = "default", mathjax = "default",
  template = "default", css = NULL, includes = NULL, keep_md = FALSE,
  lib_dir = NULL, pandoc_args = NULL, extra_dependencies = NULL, ...)

`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`
`center`	`TRUE` to vertically center content on slides
`slide_level`	Level of heading to denote individual slides. If `slide_level` is 2 (the default), a two-dimensional layout will be produced, with level 1 headers building horizontally and level 2 headers building vertically. It is not recommended that you use deeper nesting of section levels with reveal.js.
`fig_width`	Default width (in inches) for figures
`fig_height`	Default width (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
`smart`	Produce typographically correct output, converting straight quotes to curly quotes, — to em-dashes, – to en-dashes, and ... to ellipses.
`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 it's size).
`theme`	Visual theme ("simple", "sky", "beige", "serif", "solarized", "blood", "moon", "night", "black", "league" or "white").
`transition`	Slide transition ("default", "none", "fade", "slide", "convex", "concave" or "zoom")
`background_transition`	Slide background-transition ("default", "none", "fade", "slide", "convex", "concave" or "zoom")
`reveal_options`	Additional options to specify for reveal.js (see https://github.com/hakimel/reveal.js#configuration for details).
`reveal_plugins`	Reveal plugins to include. Available plugins include "notes", "search", "zoom", "chalkboard", and "menu". Note that `self_contained` must be set to `FALSE` in order to use Reveal plugins.
`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 the official 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. Note that if you don't use the "default" template then some features of `revealjs_presentation` won't be available (see the Templates section below for more details).
`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.
`pandoc_args`	Additional command line options to pass to pandoc
`extra_dependencies`	Additional function arguments to pass to the base R Markdown HTML output formatter `rmarkdown::html_document_base()`.
`...`	Ignored

In reveal.js presentations you can use level 1 or level 2 headers for slides. If you use a mix of level 1 and level 2 headers then a two-dimensional layout will be produced, with level 1 headers building horizontally and level 2 headers building vertically.
