tidyMacro Fill Scale for ggplot2

Apply the tidyMacro color palette to the fill aesthetic in ggplot2 plots. This scale is particularly useful for bar charts, area plots, and confidence bands in impulse response visualizations.

Usage

scale_fill_tidyMacro(
  palette = tidyMacro_colors,
  discrete = TRUE,
  reverse = FALSE,
  ...
)

Arguments

palette

Character vector of hex colors. Default is tidyMacro_colors.

discrete

Logical. If TRUE (default), creates a discrete scale.

reverse

Logical. If TRUE, reverses the order of colors. Default is FALSE.

...

Additional arguments passed to discrete_scale.

Value

A ggplot2 fill scale that can be added to a plot.

Details

This function creates a discrete fill scale using the tidyMacro palette. If the number of groups exceeds the 14 available colors, the palette will be recycled with a warning.
