Одна ошибка, с которой вы можете столкнуться в R:
Error in setwd("C:/Users/UserName/Desktop") :
cannot change working directory
Эта ошибка возникает, когда вы пытаетесь установить рабочий каталог в R, но неправильно указываете часть пути к файлу.
В этом руководстве рассказывается, как именно исправить эту ошибку.
Как воспроизвести ошибку
Предположим, я пытаюсь установить следующий рабочий каталог в R:
#attempt to set working directory
setwd("C:/Users/Bob/Documents/My Folder Name")
Error in setwd("C:/Users/Bob/Documents/My Folder Name") :
cannot change working directory
Я получаю сообщение об ошибке, потому что эта папка не существует на моем компьютере.
Как исправить ошибку
Самый простой способ исправить эту ошибку — изменить путь к файлу, чтобы он указывал на правильную папку:
#set working directory
setwd("C:/Users/Bob/Documents/Correct Folder Name")
Обратите внимание, что я не получаю сообщение об ошибке, потому что R смог успешно изменить рабочий каталог.
Я могу подтвердить, что рабочий каталог успешно изменился, используя функцию getwd() для получения текущего рабочего каталога:
#get current working directory
getwd()
"C:/Users/Bob/Documents/Correct Folder Name"
Распространенные причины ошибок
Существует несколько причин, по которым вы можете получить это сообщение об ошибке в R. Общие причины включают:
- Вы просто неправильно указали путь к файлу.
- Вы включили недопустимые символы в путь к файлу.
- У вас нет разрешения на доступ к пути к файлу.
Если вы столкнулись с этой ошибкой, обязательно проверьте эти три распространенные проблемы и при необходимости исправьте их.

The “cannot change working directory” R file error message is an odd little message in that while it is a coding problem it may not result from an R code mistake. Rather it is a problem that arises from trying to change a root directory to a non-existing name. This makes it an unusual problem and fortunately one that is easy to fix within the R console.
The circumstances of this problem.
The “cannot change working directory” error message occurs when using the setwd() function to change the working directory in the format of setwd(“~/”) or entering an invalid data directory name. Normally a file is placed in the default working directory. However, there are circumstances where you might want to change the current working directory within your r script file. This has the advantage that it automatically resets itself when the project or dataset is reloaded. As a result, it is a handy tool for saving and loading files from a different directory path other than the default directory path. This comes in handy when you know the file location for 2 different files or more in the project directory.
What is causing this problem?
The “cannot change working directory” error message is caused by an operating system not recognizing “~/” as indicating a root directory or pointing to an invalid folder name. As a result, the software is looking for a non-existent folder. This causes it to return this message because it cannot change the working directory.
# r error cannot change working directory r code
> getwd()
[1] "C:/Users/Owner/Documents/R/error test"
> setwd("C:/Users/Owner/Documents/R/test")
Error in setwd("C:/Users/Owner/Documents/R/test") :
cannot change working directoryIn this case, we got the message because we entered an invalid folder. In most systems using setwd(“~/”) will simply change the working directory to the root directory. However, there are some systems where “~/” is not recognized resulting in this message. Fortunately, small a change in syntax can fix the problem.
How to fix this problem.
Fixing this problem is simply a matter of eliminating the “~/” reference from your script. Because the setwd() function is the set working directory function, you can use it to set the current directory in your code. All you need to do is set it to the file path folder you are looking for. The getwd() function is similar to the dose “dir” command except that it gets you to the current working directory in your r console workspace.
# r error cannot change working directory solution code
> getwd()
[1] "C:/Users/Owner/Documents/R/error test"
> setwd("~/")
> getwd()
[1] "C:/Users/Owner/Documents"To get the same effect as this example R code you simply need to substitute the name of the specific project directory you want to go to in the character string here in place of “~/”. To get the current working directory just use the getwd() function and make the needed adjustments to get the file location folder or absolute filepath that you want as your current directory.
# cannot change working directory r error solution example code
> getwd()
[1] "C:/Users/Owner/Documents/R/error test"
> setwd("C:/Users/Owner/Documents")
> getwd()
[1] "C:/Users/Owner/Documents"In this example, we simply define the working directory as “C:/Users/Owner/Documents” to make the desired change. It may not be as elegant or short as the other version but it works. In the situation where you have an erroneous folder or file system name simply correct it in the home directory so that it is a valid name.
This is a simple problem to solve but you are only likely to get it by miss typing a folder name. If you get it for “~/” then you just have to specify where you want to put it and it will work. In both cases, you will fix the problem.

In most situations, «Error in setwd(dir): cannot change working directory» appears when the directory set doesn’t exist at all. Perhaps, you can check the working directory by running getwd() function to verify the location first. Also, check if you used / rather than to set the location.

In this article you’ll learn how to deal with the “Error in setwd() : cannot change working directory” in the R programming language.
Table of contents:
Let’s take a look at some R codes in action:
Example 1: Reproduce the Error in setwd() : cannot change working directory
In this section, I’ll explain how to replicate the error message “cannot change working directory” in R.
Let’s assume that we want to set our working directory to a folder called “Some Folder” on our Desktop using the setwd function.
Then, we might try to do that as shown below:
setwd("C:/Users/Joach/Desktop/Some Folder") # Try to use non-existing folder # Error in setwd("C:/Users/Joach/Desktop/Some Folder") : # cannot change working directory
Unfortunately, the RStudio console returns the error message “cannot change working directory”.
The reason for this is that the directory we are trying to access does not exist. We might have specified the folder name wrong, or the path before the folder name is not existing.
Example 2: Fix the Error in setwd() : cannot change working directory
We can solve this problem by specifying the path correctly. In this example, the problem was that the folder “Some Folder” does not exist on my Desktop. For that reason, I can avoid the “Error in setwd() : cannot change working directory” by setting the working directory directly to my Desktop:
setwd("C:/Users/Joach/Desktop/") # Properly specify setwd
Executing the previous R code does not lead to any errors.
Video, Further Resources & Summary
Do you need more information on the R code of this post? Then you may want to watch the following video tutorial of my YouTube channel. In the video, I illustrate the R code of this tutorial:
The YouTube video will be added soon.

You have learned in this tutorial how to avoid the “Error in setwd() : cannot change working directory” in the R programming language. In case you have any additional questions, let me know in the comments.
One error you may encounter in R is:
Error in setwd("C:/Users/UserName/Desktop") :
cannot change working directory
This error occurs when you attempt to set the working directory in R, but you misspell some part of the file path.
This tutorial shares exactly how to fix this error.
How to Reproduce the Error
Suppose I attempt to set the following working directory in R:
#attempt to set working directory
setwd("C:/Users/Bob/Documents/My Folder Name")
Error in setwd("C:/Users/Bob/Documents/My Folder Name") :
cannot change working directory
I receive an error because this folder does not exist on my computer.
How to Fix the Error
The easiest way to fix this error is to change the file path to point to the correct folder:
#set working directory
setwd("C:/Users/Bob/Documents/Correct Folder Name")
Notice that I don’t receive an error because R was able to successfully change the working directory.
I can confirm that the working directory successfully changed by using the getwd() function to get the current working directory:
#get current working directory
getwd()
"C:/Users/Bob/Documents/Correct Folder Name"
Common Reasons for Errors
There are several reasons for why you may receive this error message in R. Common reasons include:
- You simply misspelled the file path.
- You included invalid characters in the file path.
- You do not have permission to access the file path.
If you run into this error, make sure to check these three common issues and fix them if necessary.

Hi,
I am getting the ‘Error in setwd() : cannot change working directory”. As per your advise, I tried fixing tge path as suggested. On trying to read the csv file I am trying to load, I now get the error message,’ could not find function “read_csv”
I’m sorry for the delayed response, I just came back from vacation. Do you still need help with your error?
As always only very basic and not useful information. Thank you for nothing!
You could share your code and explain your problem in some more detail, instead of just being rude. I’m happy to help.

Hey, Joachim
I’m trying to change the directory on my android phone in the “R compiler”. Actually, I’ve no clue how to write the right pass to the needed folder ( the primary storage/r/lab1)
I’ll be crazy grateful, if u can help me with this.
Best regards,
Susan.
Unfortunately, I have never done this myself. However, I have recently created a Facebook discussion group where people can ask questions about R programming and statistics. Could you post your question there? This way, others can contribute/read as well: https://www.facebook.com/groups/statisticsglobe
I am using r-studio on Fedora36. My problem is with Bioconductor packages it seems because most packages upon installation throws me the “unable to write to path” and “can’t update packages” error messages. But the packages that it lists are not the package i want to install (maybe prerequisites). Now i tried to start rstudio from the terminal with sudo and the problem ofc doesn’t occur it can overwrite anything it want. But the first problem with this workaround is that working directory is locked (/root) (at least i cannot seem to change it).
If you have any thoughts on this thanks in advance. Probably i am missing a very simple solution.
Best regards

Please excuse the late response. I was on a long holiday so unfortunately I wasn’t able to reply sooner. Still need help with your code?
I do, I’m having the same issue as them and am on mac.
My code is setwd(“/Users/jaiden/Desktop/CoffeeOrder”)
My path file is the same Users/jaiden/Desktop/CoffeeOrder
Sorry for the late response. Do you still need help?
setwd(“C:/Users/Joach/Desktop/”) # Properly specify setwd
Error in setwd(“C:/Users/Joach/Desktop/”) :
cannot change working directory
As you have suggested to use this code : setwd(“C:/Users/Joach/Desktop/”) # Properly specify setwd
to solve the error (file, “rt”)
I just get the above error instead
Error in setwd(“C:/Users/Joach/Desktop/”) :
cannot change working directory
Can you help me out with that?
Thank you in advance
“C:/Users/Joach/Desktop/” is a placeholder for a path that works on my computer. You would have to insert your own file path instead. You can learn more about file paths here.

Error in setwd(x) : cannot change working directory
The text was updated successfully, but these errors were encountered:
Is the session fresh? Does the path to the out directory contain spaces?
It was a fresh session. Unless I’ve specified otherwise, the out directory is the same as the working directory, correct? If so, then there are not any spaces. This morning, I had a thought to try creating a new report from the R GUI, rather than from within RStudio. While I had RStudio running, I started the R GUI, loaded the reports package, and typed «new_report(‘new’)». Suddenly, that project opened in RStudio. I tested knitting the .*Rmd file and producing the other outputs, and it all worked fine. I happy to work with the 15-second extra step, but still don’t know is causing the original issue in RStudio. Weird. Thanks.
Hmm. I have not updated to the newest RStudio because I noticed cut and paste issues as has been the case with previous version on some Windows machines.
I will leave this issue open and test this myself with the newest RStudio and try to track the problem down. Sounds, at the moment, to be something RStudio is doing in this latest release.
Can I ask you to test some of this theory by installing an older version of RStudio and try the same procedure. Here is the version I am using:
Hmm just tried 0.98.501 and there were no problems. In RStudio what does getwd() give you?
Strange. Since you didn’t run into a similar problem with RStudio 0.98, I wonder if it has something to do with Windows 7 or my new machine. At any rate, getwd() gives me the correct (default) working directory: «C:/Program Files/R/R-3.0.2». Also, from within RStudio, I can change the working directory with setwd(). Like I mentioned, for now, I can use the R GUI to set up the report directory, then do the actual work with RStudio. Thanks.
Can you try setting the working directory to somewhere other than the default working directory? Perhaps your desktop?

The issue can be resolved by granting Read & execute permissions to ALL APPLICATION PACKGES to the folder you are trying to change their working directory to:
- In File Explorer, right click on the folder you want to use as working directory, and select Properties.
- Select Security and click Edit. to change permissions.
- Click Add.

- Enter ALL APPLICATION PACKAGES in Enter the object names to select and click Check Names. Click OK.
- Select Read & execute under the Allow column. Click OK and OK.
I will update the docs to point out this change. Thank you for bringing it to our attention.

In this article, we focus on how we can fix the “cannot change working directory” error in the R programming language.
One error that one may encounter in R is:
Error in setwd("C:/Bhuwanesh/gfg") :
cannot change working directory
Such an error occurs when we try to set a working directory in R, but a part of the file path is misspelled.
When this error might occur:
Let’s try to set the following working directory in R.
Example:
R
setwd("C:/Bhuwanesh/gfg")
Output:
We received the above error because there is no folder by the name of gfg in our local system.
Reasons for the occurrence of this error:
There can be a lot of reasons for which such an error might occur in R. Some of the reasons are the following:
- When the file path name is misspelled.
- Invalid characters are used in the file path.
- We do not have permission to access a particular file path.
- File exists but there are some other restrictions that exist for compilers.
Fixing:
We can fix the error easily by altering the wrong file path to the correct file path.
Example:
R
setwd("C:/Bhuwanesh/GeeksforGeeks/")
Output:
Output
This time we didn’t receive any error as the R compiler was successfully able to set the working directory. In order to make sure that the working directory has been changed successfully we can use the getwd() function to get the status of the current working directory.

The working directory in R is the folder where you are working. Hence, it’s the place (the environment) where you have to store your files of your project in order to load them or where your R objects will be saved.
- 1 Get working directory
- 1.1 Getwd function
- 2 Set working directory
- 2.1 Setwd function
- 2.2 Change working directory in RStudio
- 2.3 Error: Cannot change working directory
- 3 Create a RStudio project

- 6 List files of the working directory
- 7 Create a file in working directory
- 8 Remove a file in working directory
- 9 Get file path and info
- 10 Copy files of your working directory
Getwd function
In case you want to check the directory of your R session, the function getwd will print the current working directory path as a string. Hence, the output is the folder where all your files will be saved.
# Find the path of your working directory
getwd()Set working directory
Setwd function
If you are wondering how to change the working directory in R you just need to call the setwd function, specifying as argument the path of the new working directory folder.
# Set the path of your working directory
setwd("My\Path")
setwd("My/Path") # EquivalentIn case you encountered the error: ‘unexpected input in setwd’, make sure to use ‘\’ or ‘/’ instead of ‘’ when writing your directory path.
There are options if you don’t want to change the slash manually:
On the one hand, you could make use of the back2ForwardSlash function of the sos package as follows.
# install.packages(sos)
library(sos)
x <- back2ForwardSlash()
# (Enter or paste the path)
setwd(x)On the other hand, since R 4.0.0 you can type:
setwd(r"(MyPath)")Change working directory in RStudio
In order to create a new RStudio project go to Session → Set Working Directory and select the option you prefer. You can set to the project directory, source file location, files pane location or set a custom path.
Error: Cannot change working directory
There are several reasons that doesn’t allow to change the working directory.
- Check you didn’t misspelled the path.
- Make sure your path doesn’t contain invalid characters, as accents.
- Make sure you have admin permissions.
- Use the double backslash or single slash.
Create a RStudio project
RStudio projects are very useful to organize our scripts in folders. Thus, when opening a project it will contain all the files corresponding to it. Also, the project folder will be set as the working directory when you open it, so everything you save will be saved in the project folder.
Navigate to File → New Project and create a new project from a New Directory or from an Existing Directory.
If you selected the option New Directory you will have to select New Project and then write a project name and path.
Once done, a .Rproj file will be created and you will be able to have a project with all your files without the need of setting a working directory each time you open R.
Create a folder inside working directory
After setting up your working directory, you can create a new folder with the dir.create function inside the main directory. For instance, you could create a new folder, set it as new working directory and come back to the main working directory the following way:
# Save your current working directory
old_wd <- getwd()
# Create a new folder
dir.create("new_folder")
# (Do your work)
# Come back to the main directory
setwd(old_wd)Moreover, you can create nested folders with the recursive argument and the file.path function. We will give a more detailed explanation of the file.path function on its corresponding section.
# Create a new folder inside other
dir.create(file.path("folder", "child_folder"), recursive = TRUE)Remove a folder inside working directory
In case you need to remove a folder, you can call the unlink function. It should be noted that setting the recursive argument to TRUE will remove all files inside the folder.
unlink("my_folder_name", recursive = TRUE)List files of the working directory
Once you set up your working directory, you may want to know which files are inside it. For that purpose just call the dir or the list.files functions as illustrated in the following example.
dir()
list.files() # EquivalentCreate a file in working directory
If you need to create a new R file inside your working directory, you can use the file.create function and specify the name of the new file as follows:
# Creating a new R file
file.create("new_file.R")
It should be noted that this command is not commonly used, as you can press Ctrl + Shift + n in RStudio or just create a new file manually. The main use of this is command is to create a batch of new R files when working on a large project.
Remove a file in working directory
In the same way as creating a new file, you can remove or delete a file inside your directory with the file.remove function typing:
# Deleting the file 'new_file.R'
file.remove("new_file.R")Get file path and info
You can also check a file path with the file.path function and even obtain information about some file using the file.info function.
# Creating some file
file.create("my_file.R")
# Path of some file
file.path("my_file.R")
# Info about our R file
file.info("my_file.R") size isdir mode mtime ctime atime exe

If needed, you can also copy and rename an R file in your directory. For that purpose, use the file.copy function. As an example, you can copy the file named ‘my_file.R’ and rename the copy as ‘my_copied_file.R’.
file.copy("my_file.R", "my_copied_file.R")
