Base R Plot Series (Part = 2): Boxplot
We introduce a "back to basics" series of R plots using only base R - no ggplot, no ggplot2. Other parts of the series:
Task: Fancy looking boxplots of Iris dataset
Method: R Studio, Base R
Dataset: Iris (in-built)
Code & Result
data(iris) # create boxplots boxplot(Sepal.Length ~ Species, data = iris, ylim = c(0, 10), xlim = c(0, 12), at = 1:3, outline = FALSE, col = c(6, 5, 7), las = 2) boxplot(Sepal.Width ~ Species, data = iris, at = 4:6, add = TRUE, outline = FALSE, col = c(6, 5, 7), las = 2) boxplot(Petal.Length ~ Species, data = iris, at = 7:9, add = TRUE, outline = FALSE, col = c(6, 5, 7), las = 2) boxplot(Petal.Width ~ Species, data = iris, at = 10:12, add = TRUE, outline = FALSE, col = c(6, 5, 7), las = 2) # add points stripchart(Sepal.Length ~ Species, vertical = TRUE, data = iris, method = "jitter", add = TRUE, pch = c(1, 2, 3), at = 1:3) stripchart(Sepal.Width ~ Species, vertical = TRUE, data = iris, method = "jitter", add = TRUE, pch = c(1, 2, 3), at = 4:6) stripchart(Petal.Length ~ Species, vertical = TRUE, data = iris, method = "jitter", add = TRUE, pch = c(1, 2, 3), at = 7:9) stripchart(Petal.Width ~ Species, vertical = TRUE, data = iris, method = "jitter", add = TRUE, pch = c(1, 2, 3), at = 10:12) # add text text(2, 9.5, labels = "Sepal.Length") text(5, 9.5, labels = "Sepal.Width") text(8, 9.5, labels = "Petal.Length") text(11, 9.5, labels = "Petal.Width") text(2, 8.75, labels = "________") text(5, 8.75, labels = "________") text(8, 8.75, labels = "________") text(11, 8.75, labels = "________")
