> Refactor dapply's/dapplyCollect's documentation - remove duplicated comments
> ----------------------------------------------------------------------------
>
> Key: SPARK-16082
> URL: https://issues.apache.org/jira/browse/SPARK-16082
> Project: Spark
> Issue Type: Bug
> Components: SparkR
> Reporter: Narine Kokhlikyan
> Priority: Minor
>
> Currently when we generate R documentation for dapply and dapplyCollect we
> see some duplicated information.
> such as:
> Arguments
> ``
> x
> A SparkDataFrame
> func
> A function to be applied to each partition of the SparkDataFrame. func should
> have only one parameter, to which a data.frame corresponds to each partition
> will be passed. The output of func should be a data.frame.
> schema
> The schema of the resulting SparkDataFrame after the function is applied. It
> must match the output of func.

> drop, dtypes, except, explain, filter, first, gapplyCollect, gapply,
> group_by, head, histogram, insertInto, intersect, isLocal, join, limit,
> merge, mutate, ncol, persist, printSchema, rename, repartition, sample,
> saveAsTable, selectExpr, select, showDF, show, str, take, unionAll,
> unpersist, withColumn, with, write.df, write.jdbc, write.json, write.parquet,
> write.text

> This happens because the @rdname of dapply and dapplyCollect refer to the
> same file.
