[jira] [Created] (SPARK-23180) RFormulaModel should have labels member

Kevin Kuo created SPARK-23180:
---------------------------------

             Summary: RFormulaModel should have labels member
                 Key: SPARK-23180
                 URL: https://issues.apache.org/jira/browse/SPARK-23180
             Project: Spark
          Issue Type: Improvement
          Components: ML
    Affects Versions: 2.2.1
            Reporter: Kevin Kuo


Like {{StringIndexerModel}}, {{RFormulaModel}} should have a {{labels}} member to facilitate constructing the appropriate {{IndexToString}} transformer to get the string labels back. Current workaround is to perform a transform then parsing the schema which is tedious.
