#2593 closed enhancement (done)

Add method to convert a Dataset into a Modifiable dataset and possibility to replace columns

Reported by: bburlacu Owned by: mkommend
Priority: medium Milestone: HeuristicLab 3.3.14
Component: Problems.DataAnalysis Version: 3.3.13
Keywords: Cc:


The default ModifiableDataset copy constructor does not copy the values, leading to potential problems when two datasets reference the same values. A factory method for the conversion Dataset -> ModifiableDataset (with value cloning) would be a better option.

Additionally, it would be more efficient to be able to replace entire columns instead of individually changing variable values per row.
