A Plot Theme for ggplot2 by xaringanthemer

Lifecycle: Experimental.

Creates ggplot2 themes to match the xaringanthemer theme used in the xaringan slides that seamlessly matches the "normal" slide colors and styles.

theme_xaringan(
  text_color = NULL,
  background_color = NULL,
  accent_color = NULL,
  accent_secondary_color = NULL,
  css_file = NULL,
  ...
)

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.
