This is more a vtk question.

vtkTable is a vtkDataObject

vtkPointData and vtkDoubleArray are not vtkDataObject and cannot be converted in a vtkDataObject.

What are you trying to achieve here ?

I am trying to use the function vtkOrderStatistics in order to compute the 20% quantiles of the point-data in Sphere-Clips.

As far as i found out it only accepts vtkDataObjects as Input.  
So maybe i should print the Point-Values in a vtkTable and use that as Input?
