depictr colour and fill scales — scale_colour

Discrete ggplot2 scales using depictr_palette(). These are the canonical colour and fill scales used throughout the package. They honour the global options(depictr.palette = ) (via depictr_palette()) and options(depictr.na_value = ) settings; see depictr_options().

Usage

scale_colour_depictr(
  n = NULL,
  palette = NULL,
  na.value = depictr_opt("na_value"),
  ...
)

scale_color_depictr(
  n = NULL,
  palette = NULL,
  na.value = depictr_opt("na_value"),
  ...
)

scale_fill_depictr(
  n = NULL,
  palette = NULL,
  na.value = depictr_opt("na_value"),
  ...
)

Arguments

n: Optional number of colours to draw from depictr_palette(). By default ggplot2 requests exactly as many colours as there are groups; pass n only to force a fixed slice of the palette.
palette: Optional palette override: a function of one argument (the number of colours) returning a character vector of colours. Defaults to depictr_palette().
na.value: Colour for NA levels. Defaults to the resolved depictr.na_value option (the muted grey "grey80" unless changed).
...: Passed to ggplot2::discrete_scale().

Value

A ggplot2 scale that can be added to a plot.
