Key points
- Plots not showing in RStudio can be caused by various reasons, such as outdated versions, closed graphic devices, changed default graphic devices, errors, warnings, or bugs.
- To diagnose the problem, check your R and RStudio versions, current and default graphic devices, code and console messages, and packages.
- To fix the problem, update your R and RStudio versions, open a new graphic device, set the default graphic device to RStudioGD, fix your code and console messages, and update your packages.
- You can also use various tools and resources provided by RStudio and its community to help you solve the problem.
Why does the RStudio plot pane fail to display plots
If you are using RStudio to create and display plots, you may have encountered a problem where your plots are not showing in the plot pane or in a new window. This can be frustrating and confusing, especially if you are unsure what is causing the issue or how to solve it.
In this blog post, I will explain why this problem may occur, how to diagnose it, and how to fix it. By the end of this post, you will be able to see your plots again and enjoy the power of R graphics.
What is RStudio and Why Use It for Plotting?
RStudio is an integrated development environment (IDE) for R, a programming language for statistical computing and graphics. RStudio provides a user-friendly interface that makes it easy to write, run, and debug R code and create and manage projects, files, packages, and data.
One of the most useful features of RStudio is the plot pane, which allows you to view and interact with your plots without leaving the IDE. You can also export your plots to PDF, PNG, or HTML formats.

RStudio uses a graphic device to display plots in the plot pane or a new window. A graphic device is a software component that handles the creation and manipulation of graphical output. R has several built-in graphic devices like PDF, PNG, or JPG. RStudio uses its graphic device, RStudioGD, which is compatible with most R graphics functions and packages.
Using RStudio for plotting has many advantages, such as:
- You can easily create high-quality plots with minimal code using the base R graphics system or popular packages like ggplot2, lattice, or plotly. Read more about how to plot graphs using ggplot2
- You can preview your plots in real-time and adjust them.
- You can zoom in and out, copy to a clipboard, or export your plots from the plot pane.
- You can use the history tab to browse through your previous plots and revisit them later.
- You can use the show output preview option to see how your plots will look in different formats or devices.
What Causes the Problem of Plots Not Showing in RStudio?
There are several possible reasons why your plots are not showing in RStudio. Some of the most common ones are:
- You have an outdated R or RStudio version incompatible with the current graphic device. Download the latest version of R and RStudio from this link.
- You have closed the graphic device manually or accidentally by using the dev.off() function or by clicking on the close button of the plot window.
- You have changed the default graphic device to something other than RStudioGD by using the dev.new() function or setting the options(device = …) argument.
- You have an error or a warning in your code that prevents the plot from generating or displaying.
- You have a bug in your code or the package you are using that causes unexpected behaviour of the graphic device.
How to Diagnose the Problem of Plots Not Showing in RStudio?
To diagnose the problem of plots not showing in RStudio, you can try the following steps:
- Check your R and RStudio versions and make sure they are up to date. You can find your R version by running R.version in the console and your RStudio version by clicking on Help > About RStudio. The latest versions of R and RStudio as of October 2023 are 4.2.1 and 1.5.1, respectively.
- Check if you have closed the graphic device by running dev.cur() in the console. This will return the number of the current graphic device. If it returns a null device, it means that there is no active graphic device, and you need to open one by running dev.new() or by plotting something.
- Check if you have changed the default graphic device by running getOption("device") in the console. This will return the name of the default graphic device used whenever you start a new session or plot something. If it returns something other than RStudioGD, you have set a different graphic device as default, and you need to change it back by running options(device = "RStudioGD").
- Check if you have any error or warning messages in your code or console that may indicate a problem with your plot. For example, if you see a message like R graphics engine version 14 is not supported by this version of RStudio, it means that you have an incompatible version of R and RStudio and need to update them. If you see a message like Error: object 'x' not found, you have a typo or a missing variable in your code, and you need to fix it.
- Check if you have a bug in your code or the package you are using that may cause an issue with the graphic device. For example, if you use the ggplot2 package, you may encounter a problem where your plots are not showing in the plot pane but only in a new window. This known bug has been reported and fixed in the latest version of ggplot2. To solve this problem, you must update the ggplot2 package by running install.packages("ggplot2") or by using the Tools > Check for Package Updates menu in RStudio.
How to Fix the Problem of Plots Not Showing in RStudio?
If you have followed the steps above and identified the cause of the problem, you can try the following solutions to fix it:
- If you have an outdated version of R or RStudio, you need to update them to the latest versions. You can update R by downloading and installing it from the official website. You can update RStudio by downloading and installing it from the official website or using the Help > Check for Updates menu in RStudio.
- If you have closed the graphic device, you need to open it again by running dev.new() or by plotting something. Alternatively, you can restart your R session using the Session > Restart R menu in RStudio, automatically opening a new graphic device.
- If you have changed the default graphic device, you must change it back to RStudioGD by running options(device = "RStudioGD"). Alternatively, you can restart your R session by using the Session > Restart R menu in RStudio, which will automatically set the default graphic device to RStudioGD.
- If you have any error or warning messages in your code or your console, you must fix them by correcting your code or updating your packages. You can also use the Tools > Global Options > Code > Diagnostics menu in RStudio to enable various features to help you find and fix errors and warnings in your code, such as syntax highlighting, code completion, or error checking.
- If you have a bug in your code or the package you are using, you need to update your code or your package to the latest version that has fixed the bug. You can also report the bug to the package developer or the RStudio community or comment below and ask for help or suggestions.
