Modify Names & Labels of Table Object in R (2 Examples)
In this tutorial you’ll learn how to adjust the names and labels of a table object in the R programming language.
Creating 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
iris_tab <- table(iris$Species) # Table of species iris_tab # setosa versicolor virginica # 50 50 50 |
iris_tab <- table(iris$Species) # Table of species iris_tab # setosa versicolor virginica # 50 50 50
Example 1: Add Column Names to Table Object Using names() Function
names(iris_tab) <- paste0("x", 1:3) # Column labels iris_tab # x1 x2 x3 # 50 50 50 |
names(iris_tab) <- paste0("x", 1:3) # Column labels iris_tab # x1 x2 x3 # 50 50 50
Example 2: Add Row Names to Table Object Using row.names() Function
iris_tab <- t(iris_tab) # Row labels row.names(iris_tab) <- "row1" iris_tab # x1 x2 x3 # row1 50 50 50 |
iris_tab <- t(iris_tab) # Row labels row.names(iris_tab) <- "row1" iris_tab # x1 x2 x3 # row1 50 50 50
