  • Add another function, e.g. $operate(), which uses the train_df() functions internally and accepts data.frame? (Should this set a state? Maybe $operate(df, train = TRUE)?)
  • Just have $train() and $predict() accept df?
  • Do the same with Graph?
  • have the %>>% operator work on df and do the necessary conversions, so that df %>>% po("removeconstants") works?

Things to consider:

  • character cols in df often "mean" factor-cols in Tasks.
