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.
