             Summary: Add a numSlices parameter to SparkR's createDataFrame
                 Key: SPARK-18335
                 URL: https://issues.apache.org/jira/browse/SPARK-18335
             Project: Spark
          Issue Type: Improvement
          Components: SparkR
            Reporter: Shixiong Zhu


SparkR's createDataFrame doesn't have a `numSlices` parameter. The user cannot set a partition number when converting a large R dataframe to SparkR dataframe. A workaround is using `repartition`, but it requires a shuffle stage. It's better to support the `numSlices` parameter in the `createDataFrame` method.
