I’ve been using LaTeX for document rendering for over five years. No one else in my department at the time used it, beyond my friend Joe (who introduced it to me). There was no pressure from my department to learn it, only a curiosity on my end for the benefits of it. The transition to LaTeX came with a concurrent transition to its sister package Beamer, which renders Powerpoint-styled presentations. Both have numerous advantages over their Microsoft equivalents.
However, I never particularly cared for Beamer. At least, I found LaTeX’s document preparation system more intuitive than Beamer’s slides preparation system. Using both will lead to proficiency, but Beamer markup remains ugly and a chore to write.
Markdown language is simple and elegant. Pandoc allows for Markdown to be translated to TeX, and ultimately a Beamer PDF. However, Pandoc is something of a chore to render. Look at all these extra commands one needs in a terminal to make even minimal changes (e.g. A simple theme, let alone a custom one) to a Pandoc call. Rmarkdown's beamer presentation works with LaTeX code. To change the output size you can use the corresponding LaTeX commands, set just before the code junk. The smallest option would be tiny. For a full overview consider e.g. Since this is how I’m used to handling Beamer (and I like occasional subsections in my slides and in the table of. ) library(rmarkdown) file.

Look at it this way. Almost the entirety of a LaTeX document is the content itself whereas it seems half (if not more) of a Beamer document is markup. Take, for example, this sample code from a lecture slide for one of my classes.
That’s a lot of manual code for one little slide.
I’ve known about Markdown language (and Pandoc) as a substitute for straight Beamer. Markdown language is simple and elegant. Pandoc allows for Markdown to be translated to TeX, and ultimately a Beamer PDF. However, Pandoc is something of a chore to render. Look at all these extra commands one needs in a terminal to make even minimal changes (e.g. a simple theme, let alone a custom one) to a Pandoc call. I don’t have time for all that when a simple Cmd-R in Textmate (or F5 in Gedit‘s LaTeX plugin) will do the same thing when the appropriate markup is included in the preamble of the document.
R Markdown is the best of both worlds. R Markdown allows for elegant Markdown code and simple means of stylizing and rendering the slides without a ton of additional commands in the terminal. It took a while to get something that was exactly what I wanted (since R Markdown has its own peculiarities), but I did and offer what follows as a guide for those looking to take advantage of R Markdown.
Beamer Rmarkdown Box
Understanding Your Markdown Document
R Markdown uses YAML for its metadata. It also does so in a manner that’s more efficient than Pandoc (or, at least, more intuitive for me). Consider my working example below.
Metadata is always at the top of a R Markdown document. I’ll explain some important YAML items below, assuming some items (e.g. title, subtitle, date, author, fontsize) are intuitive.
The output section designates how the Markdown language will be processed. You can insert html_document if HTML is the desired output, though I’m assuming the preferred output here is a Beamer PDF.
After beamer_presentation, enter a new line, hit the space bar four times and add miscellaneous options. In the working example above, I commented out two options. When keep_tex is true, the compiling will also spit out a .tex file of the Markdown document. When toc is true, a table of contents is rendered after the title frame. In my case, I don’t want a .tex output in addition to the PDF (unless I’m doing some debugging) and I like my table of contents after my slides.1
The next option is an important one and it took me a while to figure out what exactly it was doing. slide_level determines how many pound signs are required for Markdown to assume you are wanting a new slide. I think the default option is one, but this may be inefficient if you want clear sections and subsections in your presentation. If slide_level is three, then Markdown output like this…
…will look like this standard TeX/Beamer markup.
Since this is how I’m used to handling Beamer (and I like occasional subsections in my slides and in the table of contents), I set slide_level to three.
Next, you can use in_header (after includes:) to determine what additional packages and style changes you want to include in what would otherwise be the preamble of your Beamer document. This is where you can get creative with stylizing a theme how you want. I also thought it mandatory because Markdown does some things with Beamer that I think are odd (e.g. giving a section title its own slide). Here’s my standard style file, for your consideration.
Most of these are cosmetic fixes (i.e. representing school colors in my presentations, which you are free to change), but some commands are quite useful. The last two commands in the above code reduce some of R Markdown’s odd vertical spacing. The four lines above that suppress R Markdown’s proclivity to create new slides that are just the section titles.
Finally, after_body is an optional command that will include whatever you want as slides material after what is otherwise the last slide of your document. Since I like table of contents after the last slide, I have simple .txt file with the following Beamer markup.
Compiling Your Markdown Document
If you’re using RStudio, compiling the R Markdown document is as simple as clicking a few buttons in the script window.
However, I tend to not like using GUIs, even if RStudio is quite useful. I do love automated scripts, though, especially R scripts in which I don’t have to specify a working directory. Toward that end, I wrote a simple script that you can treat as executable (assuming you’re on a Linux or Mac machine) to automatically compile your Markdown documents.
This process assumes you have just one .Rmd file per directory, which should not be a drastic change for LaTeX users. Given LaTeX’s proclivity to create log files and additional auxiliary files with every compile, LaTeX users (like me) tend to get in the habit of having one directory for each document.
Save that script with a .R extension and allow your Linux or Mac operating system to treat it as executable. You should be good to go after that.
An Example R Markdown Document
From there, the rest involves learning how simple of a language Markdown is. There are numerous cheatsheets.
Here’s a sample document I created in Markdown for illustration purposes. This is the output from compiling it with my R script.

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').
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 Kamen rider 555 ps2 iso download. 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.
