Before you start analyzing data, you need to set up your working environment. In this course, you'll use R as your programming language and RStudio as the interface to write and run R code more efficiently.

What You'll Need

• R: a programming language used for data analysis;
• RStudio: an integrated development environment (IDE) that improves the user experience of working with R.

Install R

1. Go to the official R website;
2. Select your operating system (Windows, macOS, or Linux);
3. Download the appropriate installer;
4. Run the installer and follow the on-screen instructions to complete the installation.

Install RStudio

1. Go to the RStudio download page;
2. Select your operating system and download the free RStudio Desktop version;
3. Run the installer and complete the installation process;
4. Make sure R is installed first, as RStudio depends on it to work properly.

Test Your Installation

After installing both R and RStudio:

1. Open RStudio from your applications or start menu;
2. In the console pane, type 2 + 2 and press Enter;
3. If you see the result 4, your setup is working correctly.
