Convert regular functional features (e.g. all individuals are observed at the same time-points) to new columns, one for each input value to the function.

Parameters

The parameters are the parameters inherited from PipeOpTaskPreprocSimple.

Naming

The new names generally append a _1, ..., to the corresponding column name. However this can lead to name clashes with existing columns. This is solved as follows: If a column was called "x" and the feature is "mean", the corresponding new column will be called "x_mean". In case of duplicates, unique names are obtained using make.unique() and a warning is given.
