lactater ggplot2 theme

The theme used by every lactater plot: axis lines, no grid, and quiet text, so the lactate curve and the threshold carry the color. Use it to make your own plots match.

Usage

theme_lactater(
  base_size = 11,
  base_family = getOption("lactater.font", ""),
  style = getOption("lactater.style", "light")
)

Arguments

base_size

Base font size, in points.

base_family

Base font family.

style

"light", "night" or "journal".

Value

a ggplot2 theme.

Details

Two options change every lactater plot:

• options(lactater.style = "night") switches to a dark version, and "journal" to a quieter print look (an ink curve with one amber accent). "light", a blue curve with a green threshold, is the default.

• options(lactater.font = "IBM Plex Sans") sets the font of the text and the annotations. The font must be installed (see systemfonts::require_font()).

The subtitle and the caption are text boxes from ggtext, so they wrap by themselves to the width of the plot. Restyle them with ggtext::element_textbox_simple() rather than ggplot2::element_text(), which cannot replace them.

Plots are ggplot2 objects, so anything else can be changed by adding layers, scales or a theme().

Examples

library(ggplot2)
ggplot(demo_data, aes(intensity, lactate)) +
  geom_point() +
  theme_lactater()
