How To Clear Environment In R Studio

How To Articles

In this article, I will guide you through the process of clearing the environment in R Studio. As an experienced R programmer, I often find myself needing a fresh start with a clean environment. Whether it is to remove unwanted objects or to simply start a new analysis, clearing the environment can be a useful skill to have.

Why Clearing the Environment?

There are several reasons why you might want to clear the environment in R Studio. For example, if you have created numerous variables or objects that are no longer needed, clearing the environment can help free up memory and improve the performance of your code. Additionally, clearing the environment can provide a clean slate for starting a new analysis or debugging a problematic script.

The Steps to Clear the Environment

To clear the environment in R Studio, follow these steps:

  1. Make sure you have R Studio open and your R script loaded.
  2. Click on the “Session” menu at the top of the R Studio window.
  3. Select “Clear Workspace…” from the drop-down menu.
  4. A dialog box will appear asking if you want to save your workspace image. If you have unsaved work that you want to keep, click “Save” and choose a location to save the workspace image. Otherwise, click “Don’t Save”.
  5. After clearing the workspace, all objects and variables that were stored in the environment will be removed.

It is important to note that clearing the environment will not affect any data or files that are saved on your computer. It only removes objects and variables that were created within the R Studio session.

Additional Tips

Here are a few additional tips to keep in mind when clearing the environment:

  • You can also use the keyboard shortcut Ctrl + Shift + F10 to quickly clear the environment in R Studio.
  • If you want to clear the environment and close all open R script files, you can choose “Restart R” from the “Session” menu instead of “Clear Workspace…”. This will completely restart the R session.
  • Before clearing the environment, make sure you have saved any important work or data that you want to keep.


Clearing the environment in R Studio is a simple yet powerful technique that can help improve the performance of your code and provide a fresh start for your analysis. By following the steps outlined in this article, you can easily clear the environment and start with a clean slate. Remember to save your work before clearing the environment, and make use of keyboard shortcuts and additional tips to streamline your workflow.
