Rename Data Object in R (2 Examples)
In this article, I’ll show how to change the name of a data object in the R programming language.
Table of contents:
Let’s dive right into the examples!
Introduction of Example Data
At first, we’ll need to create some example data:
my_data <- data.frame(x1 = 1:5, # Create data frame x2 = letters[6:2], x3 = "x") my_data # Print data frame
As you can see based on Table 1, the exemplifying data is a data frame having five rows and three columns.
Example 1: Change Name of Data Frame Object
In Example 1, I’ll show how to rename our data frame object in R.
For this, we can simply create a new data object as a duplicate of our old data object using the assignment operator:
new_data <- my_data # Rename data frame object new_data # Print renamed data frame object
By executing the previous R code we have created Table 2, i.e. a data frame called new_data that contains exactly the same values and columns as our input data frame.
Note that our data frame exists twice at this point (i.e. once with the name my_data and once with the name new_data). In the next example, I’ll explain how to change that!
Example 2: Remove Old Data Frame Object from Workspace
In Example 2, I’ll illustrate how to delete our old data frame from our global environment in RStudio.
For this, we can apply the rm function to the name of our original data frame:
rm(my_data) # Remove old data frame object
If we now try to print our old data frame to the RStudio console, we can see that it does not exist anymore:
my_data # Old data frame does not exist anymore # Error: object 'my_data' not found

In this R programming post you have learned how to rename a data frame object. Please note that we could apply the same type of R code to other data classes such as vectors or lists as well.
