theme_economist() Function – Change ggplot2 Theme in R (4 Examples)

In this article, I’ll demonstrate how to use the theme_economist theme of the ggplot2 package in R.

Preparing the Examples

data(iris)                                            # Load example data frame
head(iris)                                            # Display head of iris data frame
#   Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# 1          5.1         3.5          1.4         0.2  setosa
# 2          4.9         3.0          1.4         0.2  setosa
# 3          4.7         3.2          1.3         0.2  setosa
# 4          4.6         3.1          1.5         0.2  setosa
# 5          5.0         3.6          1.4         0.2  setosa
# 6          5.4         3.9          1.7         0.4  setosa
install.packages("ggplot2")                           # Install ggplot2 package
library("ggplot2")                                    # Load ggplot2 package
install.packages("ggthemes")                          # Install ggthemes package
library("ggthemes")                                   # Load ggthemes package

Example 1: Create ggplot2 Density Plot Using theme_economist() Function

ggplot(iris,                                          # Apply theme_economist Function
       aes(x = Petal.Length,
           fill = Species)) +
  geom_density(alpha = 0.5) +
  theme_economist()

Example 2: Create ggplot2 Boxplot Using theme_economist() Function

ggplot(iris,                                          # Apply theme_economist Function
       aes(x = Petal.Length,
           fill = Species)) +
  geom_boxplot() +
  theme_economist()

Example 3: Create ggplot2 Scatterplot Using theme_economist() Function

ggplot(iris,                                          # Apply theme_economist Function
       aes(x = Petal.Length,
           y = Petal.Width,
           col = Species)) +
  geom_point() +
  theme_economist()

Example 4: Create ggplot2 Barchart Using theme_economist() Function

ggplot(aggregate(Petal.Width ~ Species, iris, mean),  # Apply theme_economist Function
       aes(x = Species,
           y = Petal.Width,
           fill = Species)) +
  geom_bar(stat = "identity") +
  theme_economist()
