Dave Mason takes us through showing an R-based visual in Power BI:
The R engine isn’t included with the installation of Power BI desktop. I won’t go into detail on this, so just know you’d need to install that separately. I had already installed the R component as part of Machine Learning Services for SQL Server 2017. I also had RStudio installed. Within Power BI desktop, take a moment to click File | Options and settings | Options to open the Options page. Then click R scripting in the list of Global Options. Here you’ll see options to set the R home directory and the desired R IDE.
