Tintin Palette Generator

Palettes generated from Tintin covers. There is one palette per cover, with a total of 24 palettes of 5 colours each. Includes functions to interpolate colors in order to create more colors based on the provided palettes.The data is based on Cyr, et al. (2004) and Wikipedia < https://en.wikipedia.org/wiki/The_Adventures_of_Tintin>.

tintin

The goal of tintin is to provide palettes generated from Tintin covers. There is one palette per cover, with a total of 24 palettes of 5 colours each. Includes functions to interpolate colors in order to create more colors based on the provided palettes.

Installation

You can install the development version of tintin like so:

remotes::install_github("pachadotdev/tintin")

Example

This is a basic example which shows you how to create a plot. We’ll plot the top five causes of injury in the tintin_head_trauma dataset that comes with the package.

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

total_head_trauma_5 <- tintin_head_trauma %>% 
  arrange(-loss_of_consciousness_length) %>% 
  filter(row_number() <= 5)

ggplot(total_head_trauma_5) +
  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_manual(values = tintin_colours$the_black_island,
    name = "Book") +
  coord_flip()

What is special about the package is being able to pass the colours as a function to ggplot2. We’ll adapt the previous example to show that case.

ggplot(total_head_trauma_5) +
  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()

# Note that I can also write the palette name as
# "cigars of the pharaoh" or even as "CiGaRS  of ThE Pharaoh"
ggplot(total_head_trauma_5) +
  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, again") +
  theme_minimal() +
  scale_fill_tintin_d(option = "cigars of the pharaoh", direction = -1) +
  coord_flip()

What happens if we need more colours than 5? The functions in the package can fix that. We’ll plot the top ten causes of injury.

total_head_trauma_10 <- tintin_head_trauma %>% 
  arrange(-loss_of_consciousness_length) %>% 
  filter(row_number() <= 10)

ggplot(total_head_trauma_10) +
  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 ten causes of injury") +
  scale_fill_manual(values = tintin_clrs(
    n = length(unique(total_head_trauma_10$book_title)), 
    option = "the black island"),
    name = "Book") +
  coord_flip()

# or alternatively

ggplot(total_head_trauma_10) +
  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 ten causes of injury") +
  scale_fill_manual(values = tintin_pal(option = "the black island")(8), 
    name = "Book") +
  coord_flip()

The use of colour instead of fill is analogous. Let’s plot the top ten causes of injury per year to see it.

library(tidyr)

total_head_trauma_y <- tintin_head_trauma %>% 
  group_by(year) %>% 
  summarise_if(is.integer, sum) %>% 
  pivot_longer(loss_of_consciousness_length:loss_of_consciousness_severity) %>%
  mutate(
    name = ifelse(name == "loss_of_consciousness_length", "Length", "Severity")
  )

ggplot(total_head_trauma_y) +
  geom_line(aes(x = year, y = value, color = name), linewidth = 1.5) +
  labs(x = "Year", y = "Intensity",
    title = "Loss of consciousness length and severity") +
  theme_minimal() +
  scale_colour_manual(
    values = tintin_pal(option = "tintin in the land of the soviets")(2), 
    name = "Cause of injury"
  )
