Sun Rui commented on SPARK-12144:
---------------------------------

@shivaram, your opinion is reasonable. It seems that read.df and write.df does 
not cover all functionalities exposed by DataFrameReader and DataFrameWriter. 
Maybe we don't need to provide these two API, but provide more wrapping 
functions in SparkR.
