Step 5: Add R to the PATH Environment Variable Manually
You must manually ensure your system's PATH environment variable is set correctly. Follow these steps to add the PATH environment variable.
1. Copy the path where R is installed to the bin folder. (usually, it is in
C:\Program Files\R\R-x.x.x\bin
)
2. Right-click on This PC and select Properties.
3. Click on Advanced System Settings and then Environment Variables.
![Environment Variables Environment Variables](/sites/tutorial2program/files/getting-started-r-env-variable.png)
4. Under System Variables, find and select Path, then click Edit.
![Edit Path Under System Variables Edit Path Under System Variables](/sites/tutorial2program/files/getting-started-r-edit-path.png)
5. Click New and paste the path.

6. Click OK to close all dialogs and apply the changes.
Step 6: Verify the Installation
Once the installation is complete, you can verify that R is installed successfully by opening a command prompt (cmd) and typing the following command:
R --version
![R Installation Verification for Windows R Installation Verification for Windows](/sites/tutorial2program/files/getting-started-r-installation-verify.png)
Now, you are all set to run R programs on your device.
To install R on your Mac, just follow these steps:
- Install VS Code
- Install Homebrew (if not installed)
- Install R
- Verify your installation
Here is a detailed explanation of each of the steps:
Step 1: Install VS Code
Go to the VS Code official website and download the zipped file. Once the download is complete, open the zipped file.
In Finder, open a new window and navigate to the Applications folder. To install the VS Code application from the zip file, drag it into the Applications folder.
You can now launch VS Code directly from the Applications folder.
Step 2: Install Homebrew
Homebrew is a package manager that simplifies the installation of software on macOS. Open the Terminal app and type the following command to install Homebrew (if it's not already installed):
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
![Homebrew Installation on Mac Homebrew Installation on Mac](/sites/tutorial2program/files/getting-started-r-homebrew-installation-mac.png)
When this installation is complete, we will use homebrew to install R.
Step 3: Install R
Now that Homebrew is installed, you can easily install Rust. In the Terminal, enter the following command:
brew install r
![R Installer for Mac R Installer for Mac](/sites/tutorial2program/files/r-run-installer-mac1.png)
This command will download and install the latest version of R on your macOS system.
Step 5: Verify your installation
Once the installation is complete, you must verify that R is correctly installed. In the Terminal, type the following command:
R

Note: The version number might differ from the one above, depending on your installed version.
Linux has various distributions, and the installation process differs slightly from one to the next. For now, we will focus on the Ubuntu distribution.
Most Linux distributions come pre-installed with Python. However, if you need to install or upgrade, follow these steps:
- Install VS Code
- Add CRAN Package
- Add CRAN gpg Key
- Install r-base
- Verify Installation
Here is a detailed explanation of each of the steps:
Step 1: Install VS Code
Open the Terminal and type
sudo apt update
This command updates your package lists to ensure you get the latest versions of your software.
Proceed to install VS Code with
sudo snap install code --classic
Step 2: Add CRAN Package
We first need to add the CRAN package to our system to install R. Use the following command to do so,
echo "deb https://cloud.r-project.org/bin/linux/ubuntu noble-cran40/" | sudo tee /etc/apt/sources.list.d/r.list
![Add CRAN Package in Ubuntu Add CRAN Package in Ubuntu](/sites/tutorial2program/files/getting-started-with-r-add-cran-package-ubuntu.png)
Step 3: Add the CRAN gpg Key
After the CRAN package is added, we need to add the CRAN gpg key; use the following command to do so,
wget -qO- https://cloud.r-project.org/bin/linux/ubuntu/marutter_pubkey.asc | sudo tee -a /etc/apt/trusted.gpg.d/CRAN_ubuntu_key.asc
![Add CRAN GPG Key on Ubuntu Add CRAN GPG Key on Ubuntu](/sites/tutorial2program/files/getting-started-with-r-add-cran-gpg-key-ubuntu.png)
Step 4: Install r-base
Now to install the complete R system, use the following command.
sudo apt install y r-base
![Install R on Ubuntu Install R on Ubuntu](/sites/tutorial2program/files/getting-started-with-r-install-r-ubuntu.png)
Step 5: Verify Installation
To verify that R has been installed successfully, use the following command,
R
![Verify R Installation on Ubuntu Verify R Installation on Ubuntu](/sites/tutorial2program/files/getting-started-with-r-verify-r-installation-ubuntu.png)
Now, you can run the R program on your device.
Run Your First R Program
First, open VS Code, click on the File in the top menu, and then select New File.
![Create a New File in VS Code Create a New File in VS Code](/sites/tutorial2program/files/getting-started-with-r-new-vs-code-file-for-r.png)
Then, save this file with a
.r
extension by clicking on
File
again, then
Save As, and type your filename ending in
.r
. (Here, we are saving it as
hello.r
).
Before coding, ensure the R extension is installed in VS Code. Open VS Code and click on Extensions on the left sidebar. Then, search for the R extension and click on install.
![Install R Extension on VS Code Install R Extension on VS Code](/sites/tutorial2program/files/getting-started-with-r-install-r-extension-vs-code.png)
Now, write the following code into your file:
message <-"Hello, World"
print(message)
Then click the run button on the top right side of your screen.
![Run R Program Run R Program](/sites/tutorial2program/files/getting-started-with-r-run-r-program.png)
You should see
Hello, World
printed on the terminal.
