[jira] [Created] (SPARK-6838) Explore using Reference Classes instead of S4 objects

Shivaram Venkataraman created SPARK-6838:
--------------------------------------------

             Summary: Explore using Reference Classes instead of S4 objects
                 Key: SPARK-6838
                 URL: https://issues.apache.org/jira/browse/SPARK-6838
             Project: Spark
          Issue Type: Improvement
          Components: SparkR
            Reporter: Shivaram Venkataraman
            Priority: Minor


The current RDD and PipelinedRDD are represented in S4 objects. R has a new OO system: Reference Class (RC or R5). It seems to be a more message-passing OO and instances are mutable objects. It is not an important issue, but it should also require trivial work. It could also remove the kind-of awkward "@" operator in S4.

R6 is also worth checking out. Feels closer to your ordinary object oriented language. https://github.com/wch/R6
