Metro color palette — scale_color

The palette based on Metro Metro colors. Use scale_color_metro_d for discrete categories and scale_color_metro_c for a continuous scale, or use the discrete argument in scale_color_metro().

Usage

scale_color_metro(
  palette = NULL,
  discrete = TRUE,
  reverse = FALSE,
  aesthetics = "color",
  ...
)

scale_color_metro_d(
  palette = NULL,
  discrete = TRUE,
  reverse = FALSE,
  aesthetics = "color",
  ...
)

scale_color_metro_c(
  palette = NULL,
  discrete = FALSE,
  reverse = FALSE,
  aesthetics = "color",
  ...
)

scale_colour_metro(
  palette = NULL,
  discrete = TRUE,
  reverse = FALSE,
  aesthetics = "color",
  ...
)

scale_colour_metro_c(
  palette = NULL,
  discrete = FALSE,
  reverse = FALSE,
  aesthetics = "color",
  ...
)

scale_colour_metro_d(
  palette = NULL,
  discrete = TRUE,
  reverse = FALSE,
  aesthetics = "color",
  ...
)

scale_fill_metro(
  palette = NULL,
  discrete = TRUE,
  reverse = FALSE,
  aesthetics = "fill",
  ...
)

scale_fill_metro_d(
  palette = NULL,
  discrete = TRUE,
  reverse = FALSE,
  aesthetics = "fill",
  ...
)

scale_fill_metro_c(
  palette = NULL,
  discrete = FALSE,
  reverse = FALSE,
  aesthetics = "fill",
  ...
)

Arguments

palette: Character name of palette. Depending on the color scale, can be one of "full", "ice", "rainbow", "complement", "contrast", "light" (for dark themes), "black_first", full_original, or black_first_original. The latter three options are especially for the Okabe-Ito color palette. The default is NULL and either "contrast" or "gradient" is used (depending on whether discrete is TRUE or FALSE), which are the two scale useful for discrete or gradient color scales, respectively.
discrete: Boolean indicating whether color aesthetic is discrete or not.
reverse: Boolean indicating whether the palette should be reversed.
aesthetics: A vector of names of the aesthetics that this scale should be applied to (e.g., c('color', 'fill')).
...: Additional arguments to pass to colorRampPalette().
