When you select the Run script icon, Power BI Desktop identifies the plot and presents it on the canvas. After you've completed the script, select the Run script icon on the right side of the R script editor title bar. With the dataframe automatically generated by the fields you selected, you’re ready to write an R script, which Power BI Desktop plots to the R default device. For fields with spaces or special characters, use single quotes. For example, access the gear field by adding dataset$gear to your R script. The generated dataframe is named dataset, and you access selected columns by their respective names. In that case, add an index field to your dataset, which causes all rows to be considered unique and prevents grouping. In certain cases, you may not want automatic grouping to occur, or you may want all rows to appear, including duplicates. Power BI Desktop automatically detects which fields you've added or removed. You can add new fields or remove unneeded fields from the Values section while working on your R script in the R script editor. Only fields that you've added to the Values section are available to your R script. Alternatively, you can also select the fields directly in the Fields pane. In the Values section of the Visualization pane, drag fields from the Fields pane that you want to consume in your R script, just as you would with any other Power BI Desktop visual. The R script editor appears along the bottom of the center pane.
