Show Only Text Labels in Scatterplot in R (2 Examples)

In this tutorial you’ll learn how to show only text labels in a scatterplot in the R programming language.

Creating Example Data

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

Example 1: Plot Only Text Labels in Base R Scatterplot

plot(x = iris$Sepal.Length,        # Draw only labels
     y = iris$Sepal.Width,
     type = "n")
text(x = iris$Sepal.Length,
     y = iris$Sepal.Width,
     labels = iris$Species)

r graph figure 1 show only text labels scatterplot

Example 2: Plot Only Text Labels in ggplot2 Scatterplot

install.packages("ggplot2")        # Install & load ggplot2
library("ggplot2")
ggplot(iris,                       # Draw only labels
       aes(x = Sepal.Length,
           y = Sepal.Width,
           label = Species)) +
  geom_text()

r graph figure 2 show only text labels scatterplot
