scale_fill_kodom: Kodom fill scale for the fill aesthetic

In ggkodom: Visualize Individual Longitudinal Trajectories

Kodom fill scale for the fill aesthetic

Description

Identical behavior to scale_color_kodom() but targets the fill aesthetic. Intended for use with geom_kodom_heatmap().

Usage

scale_fill_kodom(
  colors = kodom_colors(),
  color_breaks = NULL,
  name = ggplot2::waiver(),
  discretize = FALSE,
  ...
)

Arguments

colors	Color vector. Defaults to kodom_colors().
color_breaks	Numeric breakpoints anchoring the gradient via scales::rescale(). For discretize = TRUE, each break adds one band: k breaks produce k + 1 bands. NULL = evenly spaced.
name	Legend title. Defaults to "value".
discretize	FALSE (default) = smooth gradient; TRUE = step bands at color_breaks.
...	Ignored.

Value

A ggplot2 scale object.

Examples

library(ggplot2)
df <- data.frame(
  subject_id = rep(1:5, each = 4),
  time = rep(1:4, 5),
  visit_month = rep(1:4, 5),
  value = rep(1:4, 5),
  hba1c = rep(1:4, 5),
  arm = rep(c("Treatment", "Control"), c(12, 8))
)
ggplot(df, aes(x = time, id = subject_id, fill = value)) +
  geom_kodom_heatmap() +
  scale_fill_kodom()
