xifeng created SPARK-34740:
------------------------------

             Summary: can class pyspark.mllib.evaluation.RegressionMetrics() accept DataFrame as the parameter?
                 Key: SPARK-34740
                 URL: https://issues.apache.org/jira/browse/SPARK-34740
             Project: Spark
          Issue Type: Improvement
          Components: MLlib
    Affects Versions: 2.4.6
            Reporter: xifeng


class pyspark.mllib.evaluation.RegressionMetrics(predictionAndObservations) can only accept  an RDD of (prediction, observation) pairs as the parameter.

Can it also accept the DataFrame as the parameter? Which would be much more convenient.
