R Extract Rows of Data Frame in Range of Values (Example Code)
This tutorial explains how to return only rows in a specific value range in R programming.
Introduction of Exemplifying 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: Conditionally Subsetting Data Frame Based on Range of Values in Variable
iris[iris$Sepal.Length > 5 & iris$Sepal.Length < 5.3, ] # Subsetting data # Sepal.Length Sepal.Width Petal.Length Petal.Width Species # 1 5.1 3.5 1.4 0.2 setosa # 18 5.1 3.5 1.4 0.3 setosa # 20 5.1 3.8 1.5 0.3 setosa # 22 5.1 3.7 1.5 0.4 setosa # 24 5.1 3.3 1.7 0.5 setosa # 28 5.2 3.5 1.5 0.2 setosa # 29 5.2 3.4 1.4 0.2 setosa # 33 5.2 4.1 1.5 0.1 setosa # 40 5.1 3.4 1.5 0.2 setosa # 45 5.1 3.8 1.9 0.4 setosa # 47 5.1 3.8 1.6 0.2 setosa # 60 5.2 2.7 3.9 1.4 versicolor # 99 5.1 2.5 3.0 1.1 versicolor |
iris[iris$Sepal.Length > 5 & iris$Sepal.Length < 5.3, ] # Subsetting data # Sepal.Length Sepal.Width Petal.Length Petal.Width Species # 1 5.1 3.5 1.4 0.2 setosa # 18 5.1 3.5 1.4 0.3 setosa # 20 5.1 3.8 1.5 0.3 setosa # 22 5.1 3.7 1.5 0.4 setosa # 24 5.1 3.3 1.7 0.5 setosa # 28 5.2 3.5 1.5 0.2 setosa # 29 5.2 3.4 1.4 0.2 setosa # 33 5.2 4.1 1.5 0.1 setosa # 40 5.1 3.4 1.5 0.2 setosa # 45 5.1 3.8 1.9 0.4 setosa # 47 5.1 3.8 1.6 0.2 setosa # 60 5.2 2.7 3.9 1.4 versicolor # 99 5.1 2.5 3.0 1.1 versicolor
