How to Apply which.max() & which.min() in R (2 Examples)
In this tutorial you’ll learn how to locate the first maximum or minimum in a data object using the which.max and which.min functions in R programming.
Construction of 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 |
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: Apply which.min() Function to Locate First Minimum
which.min(iris$Petal.Width) # Apply which.min function # [1] 10 |
which.min(iris$Petal.Width) # Apply which.min function # [1] 10
Example 2: Apply which.max() Function to Locate First Maximum
which.max(iris$Petal.Width) # Apply which.max function # [1] 101 |
which.max(iris$Petal.Width) # Apply which.max function # [1] 101
