Error: Vector Memory Exhausted (Limit Reached?) [FIXED]

Encountering Error: Vector Memory Exhausted? We have simple ways to troubleshoot the issue.

The RStudio IDE(integrated development environment) uses the Qt framework for its graphical user interface and is partially written in C++ programming language. Users who pay for a Base plan, $4,995, roughly comparable to $417 per month; standard $9,995, the closest approximation to $833 per month, still have some problems. Let’s talk about one of these concerns, error: vector memory exhausted (limit reached?).

Furthermore, J. J. Allaire, the innovator of the programming language ColdFusion, founded RStudio, PBC (public benefit corporation) that produces the RStudio IDE. The majority of the code is created in Java. JavaScript is another language that is implemented. in order to reflect its expansion into other programming languages, such as Python, RStudio announced that it would change its name to Posit in October.

While millions of people download and use RStudio open-source products on a daily basis, thousands of businesses and individuals also have a need to purchase RStudio commercial products offline or online.

Additionally, it is available in two formats: RStudio Desktop is a standard desktop program, but RStudio Server operates on a remote server and offers access to RStudio via a web browser. RStudio Desktop and RStudio Server both have free and premium (commercial) editions available. Prepackaged distributions of RStudio Desktop are available for Windows, Linux, and macOS. Red Hat Linux, CentOS, Ubuntu, Debian, OpenSUSE, and SLES are supported by RStudio Server and Server Pro.

What Is Error: Vector Memory Exhausted (Limit Reached?)

This error occurs when you are working on a massive set of data, and your Rstudio needs more allotted memory. Vector Memory Exhausted limit reached error can also happen when your system needs more RAM for the present work.

When you encounter a vector memory exhausted limit reached error, it means that Rstudio has used up all of the available memory on the computer system. Since different systems have different amounts of RAM installed, you’ll see an error if your RAM is insufficient for the task. Seeing such errors while working can be extremely frustrating, which is why we have another simple guide for you today.

What Causes Error: Vector Memory Exhausted (Limit Reached?)

If you are encountering the error: vector memory exhausted limit reached, It means your RStudio has reached its limit space. To view a thorough breakdown of your memory usage, click the triangle drop-down and select “Memory Usage Report.” The index will change from green to yellow, yellow to orange, and eventually red when you run out of memory if your memory usage begins to approach your memory limit.

The error vector memory exhausted limit reached can also occur if your system’s RAM is insufficient for the task at hand. The ideal RAM for RStudio projects is 8 to 16 GB. The more RAM you install, the better and smoother your experience. RAM makes your system run more efficiently. RAM installation is simple.

Additionally, the error vector memory exhausted limit reached is not like other errors; the solution is not as simple and straightforward as restarting your phone. However, just like our other guides, we will show you the simplest and quickest solution to fix the error.

How To Fix Error: Vector Memory Exhausted (Limit Reached?)

Error: Vector Memory Exhausted (Limit Reached?) can be resolved in a number of ways. Restarting the system or the application won’t solve the problem, so I suggest you avoid wasting your time. It is unlike other errors, which can usually be resolved by simply restarting your router. You must possess the necessary intellect to fully understand the cause of this error.

Furthermore, RStudio errors are frequently a little complex, so you must first comprehend the error. Our most recent guide covered the error that occurs when the file name, location, or file path’s character sequence is formatted incorrectly.

In addition, after investigating the problem, we discovered that fixing it is not that difficult. Let’s get started since we’ve listed the solutions to this error.

1 Look For A Computer System With More RAM.

2 Use Parallel Computing.

3 Change r_max_vsize in Rstudio.

4 Increase Memory Manually in R.

Look For A Computer System With More RAM

An insufficient amount of RAM on the system is one of the many causes of Vector Memory Exhausted. You need enough RAM if you are working on a larger file. RStudio has the answer for you if you’re wondering how much RAM would be sufficient for your system or work.

Furthermore, if you are unclear about what RAM accomplishes and how it will assist you with your work, RAM makes your system run faster, improving the user experience. Additionally, any computer technician may install RAM on your Computer. If you have RStudio installed on your system but subsequently add more RAM, you will need to redownload RStudio to use the additional RAM.

Use Parallel Computing

A kind of processing known as parallel computing involves running several computations or processes concurrently. Huge problems may frequently be broken down into smaller ones, which can all be handled at once.

There are many parallel packages for RStudio. Parallel computing helps a lot in programming. It saves your time and allows you to work faster.

. cl <- makeCluster(2) #starting a cluster

#cl <- makeForkCluster(8)

#stopCluster(cl) #Stopping cluster

  • Sending libraries to Clusters

Change r_max_vsize in Rstudio

RStudio terminal
terminal in RStudio

The following commands should be entered in your terminal to modify r max vsize in RStudio:

1, cd ~

2, Touch.Renviron

3, open .Renviron

Save the following line as the file’s first one once.Renviron has opened:

4 lastly, Save r_max_vsizwe = ___GB.

  • Change r_max_vsize on the Command Line.

R max vsize will be modified using the next line on the command line:


On the other hand, you may expand RStudio memory on Windows by using the memory.limit() method.

Increase Memory Manually in R

R language
R language installation

1 The first step is to right-click the R software icon on your desktop and select Properties.

2 Next, locate the Target field on the Shortcut tab.

3 Then, modify the target field by adding – -max-mem-size= __amount of memory you require.

4 After that, the previous code will then allot the R program to the specified amount of memory.

5 Lastly, Once you have clicked OK, you are finished.


We hope that one of the solutions we provided above will assist you in resolving this problem. Understanding why the error Vector Memory Exhausted is even appearing is the first thing you should do after viewing it. It often happens when your Computer needs extra RAM. Your system and even the user experience can benefit from RAM, as we have already mentioned above. Error Vector Memory Exhausted, however, may also appear for other reasons.

Additionally, it might happen when your RStudio uses all the RAM assigned to it. Pay attention to the memory storage RStudio allotted if you are working on a bigger file. To prevent this issue, you can clean the workspace. The error is also quite complex. However, there are simple solutions available. Parallel computing is another option that you have, and it will benefit you in many ways. To get around the problem, you can manually increase the memory capacity for RStudio.

In conclusion, we’ve covered the easiest methods for assisting you in troubleshooting the situation. Visit Emopulse for more guides like this one.

How do I reset R console?

Press Ctrl and L simultaneously inside R. The console should now be emptied, and the screen will now be refreshed.

Is R good for big data?

Big data works wonderfully with R. However, as R is bound by the amount of RAM in the operating system, you need a workflow.

How do I update the R version?

To check for R updates, select "Check for R Updates" from the "R" menu. When you do that, R will display the version number you're currently using and let you know whether you can download a more recent version.

How much RAM do I have?

The Device Specifications section may be found by opening Settings, then System, and next About. The amount of RAM you now have should be indicated on a line labelled Installed RAM.

How much RAM do I need for R?

Having as much RAM as possible is ideal because R uses a lot of memory. The amount of RAM you can allot to a single instance if you employ virtual machines could be constrained. Then, I advise buying as much RAM as you can and considering utilizing many nodes.
