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.
Table of contents:
It’s time to dive into the example:
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
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
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.
