Lifecycle: Maturing

Creates ggplot2 themes to match the xaringanthemer theme used in the xaringan slides that seamlessly matches the "normal" slide colors and styles. See vignette("ggplot2-themes") for more information and examples.

theme_xaringan(
  text_color = NULL,
  background_color = NULL,
  accent_color = NULL,
  accent_secondary_color = NULL,
  css_file = NULL,
  set_ggplot_defaults = TRUE,
  text_font = NULL,
  text_font_use_google = NULL,
  text_font_size = NULL,
  title_font = NULL,
  title_font_use_google = NULL,
  title_font_size = NULL,
  use_showtext = TRUE
)

Arguments

text_color

Color for text and foreground, inherits from text_color

background_color

Color for background, inherits from background_color

accent_color

Color for titles and accents, inherits from header_color

accent_secondary_color

Color for secondary accents, inherits from text_bold_color

css_file

Path to a xaringanthemer CSS file, from which the theme variables and values will be inferred. In general, if you use the xaringathemer defaults, you will not need to set this. This feature lets you create a ggplot2 theme for your xaringan slides, even if you have only saved your theme CSS file and you aren't creating your CSS theme with xaringanthemer in your slides' source file.

set_ggplot_defaults

Should defaults be set for ggplot2 geoms? Defaults to TRUE. To restore ggplot's defaults, or the previously set geom defaults, see theme_xaringan_restore_defaults().

text_font

Font to use for text elements, passed to sysfonts::font_add_google(), if available and text_font_use_google is TRUE. Inherits from text_font_family. If manually specified, can be a google_font().

text_font_use_google

Is text_font available on Google Fonts?

text_font_size

Base text font size, inherits from text_font_size, or defaults to 11.

title_font

Font to use for title elements, passed to sysfonts::font_add_google(), if available and title_font_use_google is TRUE. Inherits from title_font_family. If manually specified, can be a google_font().

title_font_use_google

Is title_font available on Google Fonts?

title_font_size

Base text font size, inherits from title_font_size, or defaults to 14.

use_showtext

If TRUE (default) the showtext package will be used to register Google fonts. Set to FALSE to disable this feature entirely, which may result in errors during plotting if the fonts used are not available locally.

Value

A ggplot2 theme
