> 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().
