Class NewRowVecTask.DataFrame

java.lang.Object
  water.Iced
      hex.NewRowVecTask.DataFrame

All Implemented Interfaces:

java.lang.Cloneable, Freezable

Enclosing class:

NewRowVecTask<T extends Iced>

public static final class NewRowVecTask.DataFrame
extends Iced

Struct to keep info about our data. Contains column ids and info about data preprocessing and expansion of vategoricals. The last element is ALWAYS treated as response variable and is never normalized nor expanded (if categorical).
