Installing RStudio:

RStudio is an integrated development environment (IDE) for R. It's available for Windows, macOS, and Linux.

1. Go to https://www.rstudio.com/products/rstudio/download/#download

2. Scroll down to find the installer for your operating system

3. Download the installer

4. Run the installer and follow the prompts

For all operating systems:

• Once the download is complete, run the installer

• Follow the installation wizard, accepting the default options unless you have specific preferences

After installation:

1. Open RStudio

2. In the console pane (usually at the bottom left), you can type R commands

3. To confirm everything is working, try typing:

   print("Hello, World!")

   If you see "Hello, World!" printed in the console, your installation is successful.

Remember, you need to install R before installing RStudio, as RStudio is an IDE that runs on top of R.
