My best advice is to keep posting ideas and joining beta programs to see what's coming. It seems to me (while I work here, this isn't based on any real inside knowledge) that we were relying more on integrating with R for analysis like K-means clustering and other advanced mathematical analytics. We're making headway into bringing those features natively into the product without the need for outside tools but there's a lot that goes into those features and a long way to go. Again, ideas are the best way to show our devs which of those features should be prioritized.
I hope this helps!
