-----------------------------------------
I'm on it. I have some troubles debugging this whole SparkR API -> backend.R -> Spark
pipeline and I'm getting error messages that are hard for me to digest, but I guess there
is no guide how to do this, so I will just take my time doing this:)

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.
