Have PBI selection feed to R-code for a visualisation

[dullyhope]

I have a few graphs in  PBI dashboard which are all created with R. Each graph shows something about a small subset of a very large dataset which the R code loads in R. I do not load that big raw dataset to PBI as it is massive. I want to be able to use some choice tool e.g. filter, slicer, parameter (?) which the user can choose in PBI. Their choice needs to feed to the R code so it can then filter the large dataset just for that value of the variable/factor. Is this possible??

hi @dullyhope 

You may try to use parameter in power bi.

https://www.mssqltips.com/sqlservertip/4475/using-parameters-in-power-bi/

https://docs.microsoft.com/en-us/power-bi/service-parameters

and for the massive dataset, it's better to use direct query in power bi.

Hi, @dullyhope ,

when you are importing data into Power BI, it is not possible to use slicers to filter data import. If your users are using Power BI Desktop to view the report, they can filter the report in Power Query. If they access the report by Power BI Service, that is not an option.

The other alternative would be to use direct query, and let the source do the calculation, instead of within Power BI. But the list of sources which are supported for direct query is not very long.
