Add Empty Row to Data Frame in R (Example)

 

In this tutorial, I’ll explain how to append an empty row to the bottom of a data frame in the R programming language.

It’s time to dive into the example:

 

Example Data

At the start, we’ll need to construct some example data:

data <- data.frame(x1 = 1:4,            # Create example data frame
                   x2 = 4:1,
                   x3 = letters[1:4])
data                                    # Print example data frame

 

table 1 data frame add empty row data frame

 

Have a look at the previously shown table. It shows that the example data frame is made up of four rows and three columns.

 

Example: Append Empty Row to Data Frame Using nrow() Function

This example shows how to bind a new empty row that contains only NA values (i.e. missing values) to the bottom of a data frame object.

To accomplish this task, we can use the nrow function as shown in the following R programming syntax:

data_new <- data                        # Create duplicate of example data frame
data_new[nrow(data_new) + 1, ] <- NA    # Add empty row containing only NA values
data_new                                # Print new data frame

 

table 2 data frame add empty row data frame

 

The output of the previous R syntax is shown in Table 2 – We have created a new data frame object called data_new that contains an additional line at the very bottom of the data frame. This new row contains only NA values.
