Defaults to TRUE. To restore ggplot's defaults, or the previously set geom

\strong{Lifecycle:} \href{https://www.tidyverse.org/lifecycle/#experimental}{Experimental}.

Provides a base plot theme for \pkg{ggplot2} to match the \pkg{xaringan} slide theme
created by \link{xaringanthemer}. The theme is designed to create a general plot
style from two colors, a \code{background_color} and a \code{text_color} (or foreground
color). Also accepts an \code{accent_color} and an \code{accent_secondary_color} that are
\link{xaringanthemer} is not required for the base theme. Use
\code{\link[=theme_xaringan]{theme_xaringan()}} or \code{\link[=theme_xaringan_inverse]{theme_xaringan_inverse()}} in xaringan slides styled by
xaringanthemer for a plot theme that matches the slide style.
