R Add Text in Multiple Lines to ggplot2 Graph (Example Code)

In this article, I’ll show how to annotate text in several lines to a ggplot2 plot in the R programming language.

Preparing the Example

data(iris)                     # Loading iris
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")
my_plot <- ggplot(iris,        # Default ggplot2 scatterplot
                  aes(x = Sepal.Width,
                      y = Petal.Length)) +
  geom_point()
my_plot

Example: ggplot2 Graphic with Several Lines of Text

my_plot +                      # Using "\n" to add multiple lines of text
  annotate("text",
           x = 3.7,
           y = 3,
           label = "Very loooooong\ntext element in\nggplot2 graphic.")
