To install R on your Mac, just follow these steps:

  1. Install VS Code
  2. Install Homebrew (if not installed)
  3. Install R
  4. 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)"

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

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:

  1. Install VS Code
  2. Add CRAN Package
  3. Add CRAN gpg Key
  4. Install r-base
  5. 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

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

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

Step 5: Verify Installation

To verify that R has been installed successfully, use the following command,
