With 10.3.1 /Pro 1.1, we can eventually integrate open-source R statistics with ArcGIS (Python scripting) for wide data analytics, in particular, combined with R-ArcGIS Bridge (R-ArcGIS/r-bridge-install · GitHub ).
If high-performance RRE (Revolution R Enterprise) is used, 64-bit ArcGIS /Pro can easily be extended to make use of the R distributed computing infrastructure.
If any experience with this aspect of practice, please share
