R Modify Position of geom_text Labels on Dodged Barplot (Example Code)

In this article, I’ll illustrate how to properly add text labels to a dodged ggplot2 barchart in R.

Setting up the Example

data(iris)                                         # Load and modify example data
iris_new <- iris[c(1:2, 51:52, 101:102),
                 c(1, 5)]
iris_new$subgroup <- LETTERS[1:2]
iris_new                                           # Display example data
#     Sepal.Length    Species subgroup
# 1            5.1     setosa        A
# 2            4.9     setosa        B
# 51           7.0 versicolor        A
# 52           6.4 versicolor        B
# 101          6.3  virginica        A
# 102          5.8  virginica        B
install.packages("ggplot2")                        # Install ggplot2 package
library("ggplot2")                                 # Load ggplot2 package
ggplot(iris_new,                                   # Labels at wrong location
       aes(x = Species,
           y = Sepal.Length,
           fill = subgroup)) +
  geom_bar(stat = "identity",
           position = "dodge") +
  geom_text(aes(Species, label = Sepal.Length))

Example: How to Position geom_text Labels on a Dodged Barchart

ggplot(iris_new,                                   # Modifying position of labels
       aes(x = Species,
           y = Sepal.Length,
           fill = subgroup)) +
  geom_bar(stat = "identity",
           position = "dodge") +
  geom_text(aes(Species, label = Sepal.Length),
            position = position_dodge(width = 1))  # Using position_dodge
