> Add pivot functionality to SparkR
> ---------------------------------
>
> Key: SPARK-15294
> URL: https://issues.apache.org/jira/browse/SPARK-15294
> Project: Spark
> Issue Type: Improvement
> Components: SparkR
> Reporter: Mikołaj Hnatiuk
> Priority: Minor
> Labels: pivot
>
> 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.
