5 Examples

5.1 Base R

5.1.1 Entire Palette Of Colors

hist(iris$Petal.Length, col = michigancolors())

hist(iris$Petal.Length, 
     col = michigancolors(),
     main = "Petal Length of Iris Flowers",
     xlab = "Petal Length")

6 Specific Color

6.1 Base R

hist(iris$Petal.Length, col = michigancolors("matthaei violet"))

plot(iris$Petal.Length, 
     iris$Sepal.Length, 
     pch = 19,
     col = michigancolors("tappan red"))

6.2 ggplot2

library(ggplot2)

6.2.1 Entire Palette Of Colors

ggplot(iris, 
       aes(x = Petal.Length, 
           fill = Species)) + 
  geom_density(alpha = .5) + 
  labs(title = "Density Plot of Species in Iris Data Set") + 
  theme_minimal() + 
  scale_fill_manual(values = michigancolors())

ggplot(iris, 
       aes(x = Petal.Length, 
           y = Sepal.Length, 
           color = Species)) + 
  geom_point() + 
  geom_smooth() + 
  labs(title = "Scatterplot of Iris Data Set") + 
  theme_minimal() + 
  scale_color_manual(values = michigancolors())

6.2.2 Specific Colors

library(ggdist) # distribution plots

ggplot(iris,
       aes(x = Species,
           y = Petal.Length,
           fill = Species)) +
  geom_dots(dotsize = 3, # dot size
            color = "black") + # outline color
  labs(title = "Petal Length by Iris Species") + 
  theme_minimal() + 
  scale_fill_manual(values = c(michigancolors("arboretum blue"),
                               michigancolors("ann arbor amethyst"),
                               michigancolors("matthaei violet")))
