scale_colour_tintin_d: Tintin Colour Scales

Description

The tintin scales provide colour maps for the different Tintin covers.

Usage

scale_colour_tintin_d(
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1,
  option = "the_blue_lotus",
  aesthetics = "colour"
)
scale_colour_tintin_c(
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1,
  option = "the_blue_lotus",
  values = NULL,
  na.value = "grey50",
  guide = "colourbar",
  aesthetics = "colour"
)
scale_fill_tintin_d(
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1,
  option = "the_blue_lotus",
  aesthetics = "fill"
)
scale_fill_tintin_c(
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1,
  option = "the_blue_lotus",
  values = NULL,
  na.value = "grey50",
  guide = "colourbar",
  aesthetics = "fill"
)

Value

A ggproto object for use with ggplot2.

Arguments

...

Other arguments passed on to ggplot2::discrete_scale(), ggplot2::continuous_scale(), or ggplot2::binned_scale() to control name, limits, breaks, labels and so forth.

alpha

The alpha transparency, a number in [0,1], see argument alpha in hsv.

begin

The (corrected) hue in [0,1] at which the color map begins.

end

The (corrected) hue in [0,1] at which the color map ends.

direction

Sets the order of colors in the scale. If 1, the default, colors are ordered from darkest to lightest. If -1, the order of colors is reversed.

option

A character string indicating the color map option to use. Options are available:

• "Tintin in the Land of the Soviets"

• "Tintin in the Congo"

• "Tintin in America"

• "Cigars of the Pharaoh"

• "The Blue Lotus" (Standard)

• "The Broken Ear"

• "The Black Island"

• "King Ottokar's Sceptre"

• "The Crab with the Golden Claws"

• "The Shooting Star"

• "The Secret of the Unicorn"

• "Red Rackham's Treasure"

• "The Seven Crystal Balls"

• "Prisoners of the Sun"

• "Land of Black Gold"

• "Destination Moon"

• "Explorers on the Moon"

• "The Calculus Affair"

• "The Red Sea Sharks"

• "Tintin in Tibet"

• "The Castafiore Emerald"

• "Flight 714 to Sydney"

• "Tintin and the Picaros"

• "Tintin and Alph-Art"

aesthetics

Character string or vector of character strings listing the name(s) of the aesthetic(s) that this scale works with. This can be useful, for example, to apply colour settings to the colour and fill aesthetics at the same time, via aesthetics = c("colour", "fill").

values

if colours should not be evenly positioned along the gradient this vector gives the position (between 0 and 1) for each colour in the colours vector.

na.value

If na.translate = TRUE, what aesthetic value should the missing values be displayed as? Does not apply to position scales where NA is always placed at the far right.

guide

A function used to create a guide or its name. See guides() for more information.

Examples

library(dplyr)
library(ggplot2)
library(tintin)

total_head_trauma <- tintin_head_trauma %>%
  arrange(-loss_of_consciousness_length) %>%
  filter(row_number() <= 5)

# discrete scale

ggplot(total_head_trauma) +
  geom_col(aes(x = cause_of_injury, y = loss_of_consciousness_length,
    fill = book_title), position = "dodge") +
  labs(x = "Cause of injury", y = "Loss of consciousness length",
    title = "Top five causes of injury") +
  theme_minimal() +
  scale_fill_tintin_d(option = "cigars_of_the_pharaoh", direction = -1) +
  coord_flip()

# continuous scale

# continuous scale
ggplot(total_head_trauma) +

   x = cause_of_injury, y = loss_of_consciousness_length,
   fill = year
 ), position = "dodge") +

   x = "Cause of injury", y = "Loss of consciousness length",
   title = "Top five causes of injury"
 ) +
