Use an HDAdvisors-branded ggplot2 theme

Usage

theme_hda(
  base_size = 14,
  base_family = "Lato",
  flip_gridlines = FALSE,
  output_format = NULL,
  html_adjust = 4,
  pdf_adjust = 7,
  ...
)

Arguments

base_size: The base size of text elements; defaults to 14
base_family: The base font family; defaults to "Lato"
flip_gridlines: Orientation of major gridlines; defaults to FALSE for y-axis
output_format: Optional manual specification of output format
html_adjust: Amount subtracted from base_size for HTML output; defaults to 4
pdf_adjust: Amount subtracted from base_size for PDF output; defaults to 7
...: Additional arguments passed to ggplot2::theme()

Value

A ggplot2::theme() object.

Details

When overriding strip text under ggplot2 >= 4.0, use ggtext::element_markdown(), never a raw ggplot2::element_text(): the branded strip element is a ggtext markdown element, and ggplot2 4.0 only merges theme elements of the same class.

The theme alone carries HDA's brand identity into an otherwise unbranded plot: bar/column fills, point colors, and line colors default to hda_colors["Blue"] (via ggplot2::element_geom()), a discrete aes(colour =)/aes(fill =) mapping cycles through the full HDA palette, and a continuous mapping uses the HDA sequential ramp (see scale_color_hda_c()) — all with no scale_*() call required. An explicit scale_*() (or a manual aes() value) always overrides these theme-carried defaults.

Examples

library(ggplot2)
ggplot(mtcars, aes(wt, mpg, color = factor(cyl))) +
  geom_point() +
  theme_hda(base_family = "")
