\arguments{
\item{incremental}{\code{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 \code{>}. For example:
\emph{\code{> - Bullet Text}}}

\item{center}{\code{TRUE} to vertically center content on slides}

\item{slide_level}{Level of heading to denote individual slides. If
\code{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.}

\item{fig_width}{Default width (in inches) for figures}

\item{fig_height}{Default height (in inches) for figures}

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

\item{fig_caption}{\code{TRUE} to render figures with captions}

\item{self_contained}{Whether to generate a full LaTeX document (\code{TRUE})
or just the body of a LaTeX document (\code{FALSE}). Note the LaTeX
document is an intermediate file unless \code{keep_tex = TRUE}.}

\item{theme}{Visual theme ("simple", "sky", "beige", "serif", "solarized",
"blood", "moon", "night", "black", "league" or "white").}

\item{transition}{Slide transition ("default", "none", "fade", "slide",
"convex", "concave" or "zoom")}

\item{background_transition}{Slide background-transition ("default", "none",
"fade", "slide", "convex", "concave" or "zoom")}

\item{reveal_options}{Additional options to specify for reveal.js (see
\href{https://revealjs.com/config/}{https://revealjs.com/config/}
for details).}

\item{reveal_plugins}{Reveal plugins to include. Available plugins include
"notes", "search", "zoom", "chalkboard", and "menu". Note that
\code{self_contained} must be set to \code{FALSE} in order to use Reveal
plugins.}

\item{highlight}{Syntax highlighting style. Supported styles include
"default", "tango", "pygments", "kate", "monochrome", "espresso",
"zenburn", and "haddock". Pass \code{NULL} to prevent syntax highlighting.}

\item{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
\code{NULL} to exclude MathJax entirely.}

\item{template}{Pandoc template to use for rendering. Pass "default" to use
the rmarkdown package default template; pass \code{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 \code{revealjs_presentation} won't be available (see the
Templates section below for more details).}

\item{css}{CSS and/or Sass files to include. Files with an extension of .sass
or .scss are compiled to CSS via \code{sass::sass()}. Also, if \code{theme} is a
\code{\link[bslib:bs_theme]{bslib::bs_theme()}} object, Sass code may reference the relevant Bootstrap
Sass variables, functions, mixins, etc.}

\item{includes}{Named list of additional content to include within the
document (typically created using the \code{\link[rmarkdown]{includes}} function).}

\item{keep_md}{Keep the markdown file generated by knitting.}

\item{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
\code{_files} appended to it.}

\item{pandoc_args}{Additional command line options to pass to pandoc}

\item{extra_dependencies}{Additional function arguments to pass to the base R
Markdown HTML output formatter \code{\link[rmarkdown:html_document_base]{rmarkdown::html_document_base()}}.}

\item{md_extensions}{Markdown extensions to be added or removed from the
default definition or R Markdown. See the \code{\link[rmarkdown]{rmarkdown_format}} for
additional details.}

\item{...}{Ignored}
}
\value{
R Markdown output format to pass to \code{\link{render}}

\description{
Format for converting from R Markdown to a reveal.js presentation.
}
\details{
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.
