I'm still working on it, hopefully by end of this weekend I can submit PR :)

I just have a quick question that which parameters should be passed from R 
command?

For fit() of wrapper class, there are many parameters 
https://github.com/apache/spark/compare/master...keypointt:SPARK-16445?expand=1#diff-ccb8590441998a896d1b74ca605b56efR62
{code}
  def fit(
  formula: String,
  data: DataFrame,
  blockSize: Int,
  layers: Array[Int],
  initialWeights: Vector,
  solver: String,
  seed: Long,
  maxIter: Int,
  tol: Double,
  stepSize: Double
 ): MultilayerPerceptronClassifierWrapper = {
{code}


And for R part, should I pass all the parameters from R command? 
https://github.com/apache/spark/compare/master...keypointt:SPARK-16445?expand=1#diff-7ede1519b4a56647801b51af33c2dd18R461
I find in the example 
(http://spark.apache.org/docs/latest/ml-classification-regression.html#multilayer-perceptron-classifier),
 only below parameters are being set, the rest are just usign default values

{code}
val trainer = new MultilayerPerceptronClassifier()
  .setLayers(layers)
  .setBlockSize(128)
  .setSeed(1234L)
  .setMaxIter(100)
{code}
