Many R packages combine R with JavaScript and output html for a richer, more interactive experience. Add support for interactive R visuals from packages such as htmlwidgets to Power BI. PBI currently requires a static image as output for the R visual.
All these JavaScript wrapping packages could be supported by allowing html-output of the relevant device (corresponding to the Viewer-pane in RStudio) http://gallery.htmlwidgets.org/
This could also improve the visualization and migration of current analytics made in libraries like rbokeh or leaflet. Directly from RStudio to PowerBI.
It would be really very interesting that PowerBI comes out with this feature. For Shiny users, the R visuals still not atractive and it is a huge blockin point to not consider Power BI as the ultimate data Viz tool.
Agreed. R visual interactivity is essential to our data when drilling is needed within the visual (which is often). Not having this reduces the usefulness of the R custom visuals.
GoogleVis is openly advertising it will host Shiny apps for free. Microsoft, you have made progress with PowerBI in comparison to other data discovery tools by providing a useful integration capability with R. Don't stop now!
