mvpa2.datasets.miscfx.aggregate_features

mvpa2.datasets.miscfx.aggregate_features(dataset, fx=<function mean>)

Apply a function to each row of the samples matrix of a dataset.

The functor given as fx has to honour an axis keyword argument in the way that NumPy used it (e.g. NumPy.mean, var).

Returns:a new Dataset object with the aggregated feature(s).
