does R script Visual supports Drill down in PowerBI ?

Hi Tn_Gartn

Currently, R visuals respond to highlighting other visuals, but you cannot click on elements in the R visual in order to cross filter other elements.

Please know the limitations

Regarding drill down feature in custom visuals, you could refer to this similar thread or this code in Github,  these suggest ways to add the drilldown property to a custom visual.

Additionally, here is a custom visual you may have a try to see if it helps.
