Reynold Xin commented on SPARK-14746:
-------------------------------------

Yea I agree - this seems a little bit too niche and the cost is somewhat high 
(introduces a new programming mode).


> Support transformations in R source code for Dataset/DataFrame

>                 URL: https://issues.apache.org/jira/browse/SPARK-14746
>             Project: Spark
>          Issue Type: New Feature
>          Components: SparkR, SQL
>            Reporter: Sun Rui

> there actually is a desired scenario mentioned several times in the Spark 
> mailing list that users are writing Scala/Java Spark applications (not 
> SparkR) but want to use R functions in some transformations. typically this 
> can be achieved by calling Pipe() in RDD. However, there are limitations on 
> pipe(). So we can support applying a R function in source code format to a 
> Dataset/DataFrame (Thus SparkR is not needed for serializing an R function.)
