theme_economist ggplot2 & ggthemes Theme in R (6 Examples)
This article illustrates how to set the ggplot2 theme to the theme_economist in the R programming language.

You’re here for the answer, so let’s get straight to the examples…
Example Data & Software Packages
Consider the example data below.
set.seed(12233665) # Set random seed data <- data.frame(x = rnorm(160), # Create example data frame y = rnorm(160), group = LETTERS[1:4]) head(data) # Print head of example data frame
Table 1 shows that our exemplifying data comprises three columns. The variables x and y are numerical, and the variable group is a character.
We also have to install and load the ggplot2 package to R, to be able to use the corresponding functions:
install.packages("ggplot2") # Install & load ggplot2 library("ggplot2")
install.packages("ggthemes") # Install ggthemes package library("ggthemes") # Load ggthemes package
In this tutorial, we’ll draw different types of graphics using the theme_economist theme. This theme can be used to reproduce the style and color theme that is used by The Economist, i.e. the international weekly newspaper.
Let’s do this!
Example 1: Draw ggplot2 Scatterplot Using theme_economist()
ggplot(data, # theme_economist scatterplot aes(x = x, y = y, col = group)) + geom_point() + theme_economist()
Example 2: Draw ggplot2 Density Plot Using theme_economist()
ggplot(data, # theme_economist density plot aes(x = x, fill = group)) + geom_density(alpha = 0.5) + theme_economist()
Example 3: Draw ggplot2 Histogram Using theme_economist()
ggplot(data, # theme_economist histogram aes(x = x, fill = group)) + geom_histogram(alpha = 0.5, position = "identity", bins = 50) + theme_economist()
Example 4: Draw ggplot2 Barchart Using theme_economist()
ggplot(aggregate(y ~ group, data, sum), # theme_economist barplot aes(x = group, y = y, fill = group)) + geom_bar(stat = "identity") + theme_economist()
Example 5: Draw ggplot2 Boxplot Using theme_economist()
ggplot(data, # theme_economist boxplot aes(x = x, fill = group)) + geom_boxplot() + theme_economist()
Example 6: Draw ggplot2 Line Plot Using theme_economist()
ggplot(data, # theme_economist line plot aes(x = x, y = y, col = group)) + geom_line() + theme_economist()
