To use R within Power BI, you must first install an R distribution for you to run and execute scripts against. In this book, we will leverage Microsoft's distribution, Microsoft R Open.

Let's walk through these setup steps together:

1. Navigate to the website https://mran.microsoft.com/download/ to download and install Microsoft R Open.
2. For the purposes of our example, you will select Download next to Microsoft R Open for Windows.
3. Once the download has completed, run the installation and accept all default settings and user agreements.
4. Next, launch a new instance of the Power BI Desktop to set up the R integration with Power BI. Click the menu options File | Options and settings | Options.
