How to Remove Data Frame Row Names in R / RStudio Console (Example Code)
This article illustrates how to avoid row names when printing data frames to the RStudio console in the R programming language.
Example Data
data(iris) # Loading iris data set head(iris) # Printing head of iris data set # 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) # Loading iris data set head(iris) # Printing head of iris data set # 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: Removing Row Names from Printed Data Frame in RStudio Console
print(head(iris), # Using print function & row.names argument row.names = FALSE) # Sepal.Length Sepal.Width Petal.Length Petal.Width Species # 5.1 3.5 1.4 0.2 setosa # 4.9 3.0 1.4 0.2 setosa # 4.7 3.2 1.3 0.2 setosa # 4.6 3.1 1.5 0.2 setosa # 5.0 3.6 1.4 0.2 setosa # 5.4 3.9 1.7 0.4 setosa |
print(head(iris), # Using print function & row.names argument row.names = FALSE) # Sepal.Length Sepal.Width Petal.Length Petal.Width Species # 5.1 3.5 1.4 0.2 setosa # 4.9 3.0 1.4 0.2 setosa # 4.7 3.2 1.3 0.2 setosa # 4.6 3.1 1.5 0.2 setosa # 5.0 3.6 1.4 0.2 setosa # 5.4 3.9 1.7 0.4 setosa
