> 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.
