Remove Multiple Data Objects Using rm Function in R (Example)

In this tutorial, I’ll illustrate how to delete several data objects from the R environment running the rm function only once in the R programming language.

The content of the article looks as follows:

It’s time to dive into the exemplifying R code…

Creating Example Data

As a first step, we’ll have to construct some data that we can use in the examples below.

data <- data.frame(x1 = 1:5,    # Creating data
                   x2 = LETTERS[1:5])
vec <- 1:10                     # Creating vector

The previous R code shows the structure of our example data: We have created one data frame object and a vector.

Example: Removing Data Frame & Vector Using rm() Function

This Example explains how to delete multiple data objects from the global R environment in one line of R code. Have a look at the rm() function in action:

rm(data, vec)                   # Apply rm()

As you have seen based on the previous R code, we simply had to insert the names of the data objects that we want to remove, separated by a comma. Have a look at your RStudio console. The data objects data and vec will not be contained in the environment anymore.

In this R tutorial you learned how to clean multiple data objects simultaneously. Let me know in the comments, in case you have any further questions.
