Create a reusable theme preset — make

Builds a theme function from ggplot2::theme() elements and an optional base theme. The returned function applies the theme to a plotit object and can be used anywhere style() is used.

Usage

make_theme(name, ..., base_theme = ggplot2::theme_minimal)

Arguments

name: Name for the theme function as a string (e.g. "style_dark").
...: Theme elements passed to ggplot2::theme().
base_theme: A base ggplot2 theme function (default: ggplot2::theme_minimal).

Value

Invisibly returns the created function.

Details

The theme function is assigned to name in the calling environment (parent.frame()) and also returned invisibly. When calling make_theme() inside another function, assign the return value explicitly – the parent.frame() assignment is lost when that function returns.

Examples

style_dark <- make_theme("style_dark",
  plot.background = ggplot2::element_rect(fill = "#1a1a1a"),
  text = ggplot2::element_text(colour = "white")
)
plotit(iris, encode(x = Sepal.Width, y = Sepal.Length)) |>
  mark_point() |>
  style_dark()
