Bold-styled Black and White Theme — theme

A modified ggplot2 black and white theme with bold text elements. By default, the plot title, subtitle, caption, axis titles, and legend title support markdown/HTML via ggtext::element_markdown().

Usage

theme_bw2(markdown = TRUE)

Arguments

markdown: Logical; if TRUE (default), the plot title, subtitle, caption, axis titles, and legend title use ggtext::element_markdown(), so labels can contain markdown/HTML such as "*italic*", "**bold**", or "log<sub>2</sub> FC". Use "<br>" for line breaks in these labels instead of "\n", which markdown/HTML rendering ignores. Axis tick labels and legend text are left as plain ggplot2::element_text() (they can still be switched to ggtext::element_markdown() manually, e.g. theme(axis.text.x = ggtext::element_markdown(angle = 45))). Note that when TRUE, further overriding one of the markdown elements (plot title/subtitle/caption, axis titles, or legend title) with ggplot2::element_text() errors in ggplot2 >= 4.0 ("Only elements of the same class can be merged"); use ggtext::element_markdown() for that override instead, or set markdown = FALSE for plain ggplot2::element_text() elements throughout.

Value

A ggplot2 theme object
