> R users are very used to transforming data using functions such as dcast (pkg:reshape2). https://github.com/apache/spark/pull/7841 introduces such functionality to Scala and Python APIs. I'd like to suggest adding this functionality into SparkR API to pivot DataFrames.
> I'd love to to this, however, my knowledge of Scala is still limited, but with a proper guidance I can give it a try.
