A View which performs a function which aggregates all the data pointed to by a common label into a single row. For example, to generate the mean trajectors of all rows in a dataset from a clustering labeling, you can use something like this:

ds is a Dataset lab is a clustering view = RowAggregateFunctionView(ds, lab, MLab.mean)

__init__ (
        self,
        dataset,
        labeling,
        function,
        )
