Get working directory
Getwd role
In case you lot desire to cheque the directory of your R session, the function getwd volition print the current working directory path as a string. Hence, the output is the binder where all your files will be saved.
# Find the path of your working directory getwd() Set working directory
Setwd part
If you are wondering how to modify the working directory in R you just need to call the setwd function, specifying as argument the path of the new working directory folder.
# Fix the path of your working directory setwd("My\\Path") setwd("My/Path") # Equivalent In instance y'all encountered the fault: 'unexpected input in setwd', brand certain to use '\\' or '/' instead of '\' when writing your directory path.
In that location are options if you don't want to modify the slash manually:
On the one hand, you could make utilise 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 paw, since R 4.0.0 you can type:
setwd(r"(My\Path)") Alter working directory in RStudio
In order to create a new RStudio project become to Session → Ready Working Directory and select the option you prefer. You can set up to the projection directory, source file location, files pane location or set a custom path.
Fault: Cannot alter working directory
In that location are several reasons that doesn't allow to alter the working directory.
- Check you didn't misspelled the path.
- Make certain 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 projection
RStudio projects are very useful to organize our scripts in folders. Thus, when opening a projection information technology will contain all the files respective to it. Also, the project folder will be prepare as the working directory when you open up it, so everything you salvage 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 selection New Directory yous will take to select New Project and and so write a projection name and path.
In one case washed, a .Rproj file will exist created and yous volition 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 within working directory
After setting upward your working directory, you can create a new folder with the dir.create function inside the main directory. For example, you could create a new binder, set information technology as new working directory and come back to the chief working directory the following fashion:
# Save your current working directory old_wd <- getwd() # Create a new folder dir.create("new_folder") # (Practise your work) # Come dorsum to the main directory setwd(old_wd) Moreover, you tin create nested folders with the recursive argument and the file.path function. We volition 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 telephone call the unlink function. It should be noted that setting the recursive argument to Truthful volition remove all files inside the folder.
unlink("my_folder_name", recursive = Truthful) List files of the working directory
Once yous set up your working directory, you may desire to know which files are within it. For that purpose merely call the dir or the list.files functions equally illustrated in the post-obit example.
dir() listing.files() # Equivalent Create a file in working directory
If you need to create a new R file within your working directory, yous can employ the file.create function and specify the proper name of the new file as follows:
# Creating a new R file file.create("new_file.R") Information technology should be noted that this control is not ordinarily used, every bit yous can press Ctrl + Shift + n in RStudio or just create a new file manually. The chief employ 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, y'all 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 tin can also bank check a file path with the file.path function and even obtain information nigh 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 new_file.R 0 Fake 666 2022-03-22 xvi:02:54 2022-03-22 sixteen:02:54 2022-03-22 16:02:54 no Copy files of your working directory
If needed, you tin can as well re-create and rename an R file in your directory. For that purpose, use the file.copy role. As an example, you tin can copy the file named 'my_file.R' and rename the copy equally 'my_copied_file.R'.
