    Hi ojbowden ,

     

    Please check the Known limitations of R visual in Power BI.

    R visuals in Power BI Desktop have the following limitations:

    • Data sizes: Data used by an R visual for plotting is limited to 150,000 rows. If more than 150,000 rows are selected, only the top 150,000 rows are used and a message is displayed on the image.

    • Output size : R visual has an output size limit of 2MB.

    • Resolution: All R visuals are displayed at 72 DPI.

    • Plotting device: Only plotting to the default device is supported.

    • Calculation times: If an R visual calculation exceeds five minutes, it causes a time-out error.

    • Relationships: As with other Power BI Desktop visuals, if data fields from different tables with no defined relationship between them are selected, an error occurs.

    • Refreshes: R visuals are refreshed upon data updates, filtering, and highlighting. However, the image itself isn't interactive and can't be the source of cross-filtering.

    • Highlights: R visuals respond if you highlight other visuals, but you can't select elements in the R visual to cross filter other elements.

    • Display devices: Only plots that are plotted to the R default display device are displayed correctly on the canvas. Avoid explicitly using a different R display device.

    • Column renaming: R visuals do not support renaming input columns. Columns will be referred to by their original name during script execution.

    • RRO installations: In this release, the 32-bit version of Power BI Desktop doesn't automatically identify RRO installations; you must manually provide the path to the R installation directory in Options and settings > Options > R Scripting.

    For reference: Create Power BI visuals using R

    And you can check whether you have install and configure R script correctly.

    For reference: Run R scripts in Power BI Desktop
