xaringanthemer

Give your xaringan slides some style with xaringanthemer within your slides.Rmd file without (much) CSS.

Installation

You can install xaringanthemer from CRAN

install.packages("xaringanthemer")

or you can install the development version of xaringanthemer from GitHub.

# install.packages("remotes")
remotes::install_github("gadenbuie/xaringanthemer")

Quick Intro

First, add the xaringan-themer.css file to the YAML header of your xaringan slides.

output:
  xaringan::moon_reader:
    css: xaringan-themer.css

Then, in a hidden chunk just after the knitr setup chunk, load xaringanthemer and try one of the theme functions.

```{r xaringan-themer, include=FALSE, warning=FALSE}
library(xaringanthemer)
style_mono_accent(
  base_color = "#1c5253",
  header_font_google = google_font("Josefin Sans"),
  text_font_google   = google_font("Montserrat", "300", "300i"),
  code_font_google   = google_font("Fira Mono")
)
```

Matching ggplot Themes

xaringanthemer even provides a ggplot2 theme with theme_xaringan() that uses the colors and fonts from your slide theme. Built on the showtext package, and designed to work seamlessly with Google Fonts.

Color and fill scales are also provided for matching sequential color scales based on the primary color used in your slides. See ?scale_xaringan for more details.

library(ggplot2)
ggplot(diamonds) +
  aes(cut, fill = cut) +
  geom_bar(show.legend = FALSE) +
  labs(
    x = "Cut",
    y = "Count",
    title = "A Fancy diamonds Plot"
  ) +
  theme_xaringan(background_color = "#FFFFFF") +
  scale_xaringan_fill_discrete()

Tab Completion

xaringanthemer is Tab friendly – use autocomplete to explore the template variables that you can adjust in each of the themes!

R Markdown Template in RStudio

You can also skip the above and just create a Ninja Themed Presentation from the New R Markdown Document menu in RStudio.
