Does an R Script run once for each dataframe returned?

[yoshy]

When using an R script as a data source, the menu gives you the option of which data.frames you want to load into the Power BI environment. If I select multiple data.frames, are those data.frames then associated with the same instance of that script? That is, if I update the data in the future, will the R script run only once to get all those tables again, or will it run once per each table returned?

HI @yoshy,

AFAIK, these r scripts are integrated with M query functions. So I suppose they will be triggered every time when the query table activeted.

Use R in Power Query Editor - Power BI | Microsoft Docs

How do you edit the R-Script to load more data so it does not create duplicate data
