[jira] [Updated] (SPARK-14303) Refactor SparkRWrappers

["Xiangrui Meng (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SPARK-14303?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Xiangrui Meng updated SPARK-14303:
----------------------------------
    Description: 
We use a single object `SparkRWrappers` (https://github.com/apache/spark/blob/master/mllib/src/main/scala/org/apache/spark/ml/r/SparkRWrappers.scala) to wrap method calls to glm and kmeans in SparkR. This is quite hard to maintain. We should refactor them into separate wrappers, like `AFTSurvivalRegressionWrapper` and `NaiveBayesWrapper`.

The package name should be `spakr.ml.r` instead of `spark.ml.api.r`.
