Order Data Frame Variable Based On Another Column in R (Example Code)

On this page you’ll learn how to order a data frame variable based on another column in R.

Introduction 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

Example: How to Order the Rows of a Data Frame Based On Multiple Columns

iris_sort <- iris[order(iris$Sepal.Length,    # Sorting a data frame based on multiple variables
                        iris$Petal.Length), ]
head(iris_sort)
#    Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# 14          4.3         3.0          1.1         0.1  setosa
# 39          4.4         3.0          1.3         0.2  setosa
# 43          4.4         3.2          1.3         0.2  setosa
# 9           4.4         2.9          1.4         0.2  setosa
# 42          4.5         2.3          1.3         0.3  setosa
# 23          4.6         3.6          1.0         0.2  setosa
