Clear Data Object from Workspace in R (3 Examples) | rm & remove Functions

 

In this R tutorial you’ll learn how to clear specific data objects from the R workspace. The tutorials relies mainly on the rm() and remove() functions.

The tutorial will consist of these content blocks:

Let’s take a look at some R codes in action!

 

Example 1: Remove One Specific Data Object

Let’s assume that we have stored the following data object x in our R workspace:

x <- 5               # Create data object

 

r workspace with data object

Figure 1: R Workspace Contains Data Object x.

 

Then we can remove this specific data object with the rm function as shown below:

rm(x)                # Apply rm function

 

r workspace empty

Figure 2: Data Object x was Removed from R Workspace.

 

The advantage of this method is that we can delete specific data objects from our workspace without removing the entire workspace.

 

Example 2: Remove Multiple Data Objects

We can also remove several data objects at once with the rm function in R. Consider the following three data objects:

x <- 5               # Multiple data objects
y <- 3
z <- "hello"

Now, we can simply specify all of these objects within the rm function in order to clear them from the R environment:

rm(x, y, z)          # Remove multiple objects

 

Example 3: rm() vs. remove() Functions

Actually, there are two different functions that can be used for clearing specific data objects from the R workspace: rm() and remove().

However, these two functions are exactly the same. You can use the function you prefer.

For illustration, I’m showing Example 1 based on the remove function:

x <- 5               # Create data object
remove(x)            # Apply remove function

The previous R code also clears the data object x from the R workspace.
