R Modify Width of ggplot2 Bars to Increase Space (Example Code)

In this R tutorial you’ll learn how to modify space and width of bars in a ggplot2 barchart.

Preparing the Example

data(iris)                       # Example data
head(iris)
#   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 & load ggplot2
library("ggplot2")
ggplot(iris,                     # Default space between bars
       aes(x = Species,
           y = Sepal.Width)) +
  geom_bar(stat = "identity")

Example: Change Space & Width of Bars in ggplot2 Barchart

ggplot(iris,                     # More space between bars
       aes(x = Species,
           y = Sepal.Width)) +
  geom_bar(stat = "identity",
           width = 0.2)
