scale_color_colorhex {see}

Color palettes from color-hex

Description

This function creates color scales based on palettes from https://www.color-hex.com/. This website provides a large number of user-submitted color palettes. This function downloads a requested color palette from https://www.color-hex.com/. and creates a {ggplot2} color scale from the provided hex codes.

Use scale_color_colorhex_d for discrete categories and scale_color_colorhex_c for a continuous scale.

Usage

scale_color_colorhex(
  palette = 1014416,
  discrete = TRUE,
  reverse = FALSE,
  aesthetics = "color",
  ...
)

scale_color_colorhex_d(
  palette = 1014416,
  discrete = TRUE,
  reverse = FALSE,
  aesthetics = "color",
  ...
)

scale_color_colorhex_c(
  palette = 1014416,
  discrete = FALSE,
  reverse = FALSE,
  aesthetics = "color",
  ...
)

scale_colour_colorhex(
  palette = 1014416,
  discrete = TRUE,
  reverse = FALSE,
  aesthetics = "color",
  ...
)

scale_colour_colorhex_c(
  palette = 1014416,
  discrete = FALSE,
  reverse = FALSE,
  aesthetics = "color",
  ...
)

scale_colour_colorhex_d(
  palette = 1014416,
  discrete = TRUE,
  reverse = FALSE,
  aesthetics = "color",
  ...
)

scale_fill_colorhex(
  palette = 1014416,
  discrete = TRUE,
  reverse = FALSE,
  aesthetics = "fill",
  ...
)

scale_fill_colorhex_d(
  palette = 1014416,
  discrete = TRUE,
  reverse = FALSE,
  aesthetics = "fill",
  ...
)

scale_fill_colorhex_c(
  palette = 1014416,
  discrete = FALSE,
  reverse = FALSE,
  aesthetics = "fill",
  ...
)

Arguments

palette

The numeric code for a palette at https://www.color-hex.com/. For example, 1014416 for the Josiah color palette (number 1014416).

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().

Note

The default Josiah color palette (number 1014416) is available without an internet connection. All other color palettes require an internet connection to download and access.
