3. Run Scripts option is not available

Hi,

In order to use R Visuals you need to first install R and enable it in Power BI Desktop

Follow these steps to use R Visuals in Query Editor:

Step 1: 

•  Load your data into Power BI Desktop

•  Get Data > CSV from the Home ribbon in Power BI Desktop

Step 2: 

•  Select the file and Select Open

•  CSV file is displayed in the CSV file dialog

Step 3: 

Once the data is loaded you will be able to see it in the Fields pane in Power BI Desktop

Step 4:

Open Query Editor  by selecting Edit Queries from the Home tab in Power BI Desktop

Step 5: 

In Transform tab, select RUN R Script and the Run R Script editor appears

Step 6: 

Enter your R Script in the R Script Editor      

   Note: You will need mice library installed in you R  environment for your script code to work properly

   library(mice)

   tempData <- mice(dataset,m=1,maxit=50,meth='pmm',seed=100)

   completedData <- complete(tempData,1)

   output <- dataset

   output$completedValues <- completedData$"SMI missing values"

Step 7: 

After selecting OK, Query Editor displays a warning about data privacy

Step 8: 

For R Scripts to run properly, all the data sources must be public

Now you can finally create your own visualizations depending upon your dataset.

Hope This Helps!!
