How to Delete Each Row in a Data Frame in R (Example Code)
This article shows how to drop each row in a data frame object in the R programming language.
Introduction of Example Data
data(iris) # Importing example data with rows 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: Removing Each Row in a Data Frame Object & Keep Only Column Names
iris_empty <- iris[0, ] # Deleting all rows in a data frame iris_empty # [1] Sepal.Length Sepal.Width Petal.Length Petal.Width Species # <0 rows> (or 0-length row.names) |
iris_empty <- iris[0, ] # Deleting all rows in a data frame iris_empty # [1] Sepal.Length Sepal.Width Petal.Length Petal.Width Species # <0 rows> (or 0-length row.names)
