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.") |
