Description

Format for converting from R Markdown to a Beamer presentation.

Usage

Arguments

TRUE to include a table of contents in the output (onlylevel 1 headers will be included in the table of contents).

The heading level which defines individual slides. Bydefault this is the highest header level in the hierarchy that is followedimmediately by content, and not another header, somewhere in the document.This default can be overridden by specifying an explicitslide_level.

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

Default width (in inches) for figures

Default height (in inches) for figures

TRUE to automatically apply the pdfcrop utility(if available) to pdf figures

TRUE to render figures with captions

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

Method to be used for printing data frames. Valid valuesinclude 'default', 'kable', 'tibble', and 'paged'. The 'default' method usesprint.data.frame. The 'kable' method uses theknitr::kable function. The 'tibble' method usesthe tibble package to print a summary of the data frame. The 'paged'method creates a paginated HTML table (note that this method is only validfor formats that produce HTML). In additionto the named methods you can also pass an arbitrary function to be usedfor printing data frames. You can disable the df_print behavior entirelyby setting the option rmarkdown.df_print to FALSE.

Beamer theme (e.g. 'AnnArbor').

Beamer color theme (e.g. 'dolphin').

Beamer font theme (e.g. 'structurebold').

Beamer R Markdown Color

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

Pandoc template to use for rendering. Pass 'default' to usethe rmarkdown package default template; pass NULL to use pandoc'sbuilt-in template; pass a path to use a custom template that you'vecreated. See the documentation onpandoc online documentationfor details on creating custom templates.

Keep the intermediate tex file used in the conversion to PDF

LaTeX engine for producing PDF output. Options are'pdflatex', 'lualatex', and 'xelatex'.

The LaTeX package to process citations, natbibor biblatex. Use none if neither package is to be used.

Whether to generate a full LaTeX document (TRUE)or just the body of a LaTeX document (FALSE). Note the LaTeXdocument is an intermediate file unless keep_tex = TRUE.

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

Markdown extensions to be added or removed from thedefault definition or R Markdown. See the rmarkdown_format foradditional details.

Beamer

Details

See the onlinedocumentation for additional details on using the beamer_presentationformat.

Creating Beamer output from R Markdown requires that LaTeX be installed.

R Markdown documents can have optional metadata that is used to generate adocument header that includes the title, author, and date. For more detailssee the documentation on R Markdown metadata.

R Markdown documents also support citations. You can find more information onthe markdown syntax for citations in theBibliographiesand Citations article in the online documentation.

Examples

4.3 Beamer presentation

To create a Beamer presentation from R Markdown, you specify the beamer_presentation output format in the YAML metadata of your document. You can create a slide show broken up into sections by using the # and ## heading tags (you can also create a new slide without a header using a horizontal rule (---). For example, here is a simple slide show (see Figure 4.3 for two sample slides):

FIGURE 4.3: Two sample slides in a Beamer presentation.

Within R Markdown documents that generate PDF output, you can use raw LaTeX and even define LaTeX macros. See Pandoc’s manual for details.

4.3.1 Themes

You can specify Beamer themes using the theme, colortheme, and fonttheme options. For example:

Figure 4.4 shows two sample slides of the AnnArbor theme in the above example. You can find a list of possible themes and color themes at https://hartwork.org/beamer-theme-matrix/.

4.3.2 Slide level

The slide_level option defines the heading level that 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:
