Method Details

reduce

R reduce(int rowDimension,
 int columnDimension,
 Aggregator aggregator)

Parameters:

rowDimension - Which of the AnyD-dimensions should be mapped to the rows of the resulting 2D structure.

columnDimension - Which of the AnyD-dimensions should be mapped to the columns of the resulting 2D structure.

aggregator - How to aggregate the values of the reduction

Returns:

A 2D data structure with aggregated values
