Narine Kokhlikyan 26afb4ce40 [SPARK-16012][SPARKR] Implement gapplyCollect which will apply a R function on each group similar to gapply and collect the result back to R data.frame ... ## What changes were proposed in this pull request? gapplyCollect() 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(). ## How was this patch tested? Added test cases for gapplyCollect similar to dapplyCollect Author: Narine Kokhlikyan <narine@slice.com> Closes #13760 from NarineK/gapplyCollect.		2016-07-01 13:55:13 -07:00
