             Summary: add gapplyCollect() for SparkDataFrame
                 Key: SPARK-16012
                 URL: https://issues.apache.org/jira/browse/SPARK-16012
             Project: Spark
          Issue Type: Sub-task
          Components: SparkR
    Affects Versions: 1.6.1
            Reporter: Sun Rui


Add a new API method called gapplyCollect() for SparkDataFrame. It does gapply on a SparkDataFrame and collect the result back to R. Compared to gapply() + collect(), gapplyCollect() offers performance optimization as well as programming convenience, as no schema is needed to be provided.

This is similar to dapplyCollect().
