How to Color Points of Scatterplot in R (2 Examples)
In this R tutorial you’ll learn how to draw a scatterplot with colors.
Setting up the Examples
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 |
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: Create Base R Scatterplot with Colored Dots
plot(iris$Petal.Length, # Drawing scatterplot with Base R iris$Petal.Width, pch = 16, col = iris$Species) |
plot(iris$Petal.Length, # Drawing scatterplot with Base R iris$Petal.Width, pch = 16, col = iris$Species)
Example 2: Create ggplot2 Scatterplot with Colored Dots
install.packages("ggplot2") # Install ggplot2 package library("ggplot2") # Load ggplot2 |
install.packages("ggplot2") # Install ggplot2 package library("ggplot2") # Load ggplot2
ggplot(iris, # Drawing scatterplot with ggplot2 aes(x = Petal.Length, y = Petal.Width, col = Species)) + geom_point() |
ggplot(iris, # Drawing scatterplot with ggplot2 aes(x = Petal.Length, y = Petal.Width, col = Species)) + geom_point()
