HI CanadianAnalyst ,

It seems like you are working with libraries of external devices, I'd like to suggest you take a look at the limits of use R script in power bi R visual:

Create Power BI visuals using R#known-limitations 

Known limitations

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.

• 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.

• 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.
