Sometimes we need measures that are far more mathematically complicated than PowerBI is capable of -- for example, computing the 75th percentile of the product of two normal distributions. This is...
Presumably the challenge with implementation is related to R being far more flexible in terms of the type of entity it can return than DAX is, but this feature would really help bring advanced analytics into the Power BI environment. Current options are either a) use R in Query Editor (analytics are then not dynamic) or b) use R custom visuals (visual consistency with standard Power BI objects is difficult / impossible to achieve). Neither is a good option.
