In MomentVon/HMtools: some small tools for hydrology modell

Description

Aggregate a array(dim >=3)* object to create a lower resolution (larger cells). Aggregation groups rectangular areas to create larger cells. The value for the resulting cells is computed with a user-specified function.

Usage

aggregateArray(OriginalWert, aggregateN, aggregateFunction = colMeans)

Arguments

OriginalWert	Original array Wert
aggregateN	integer. Aggregation factor expressed as number of cells in each direction (horizontally and vertically). Or two integers (horizontal and vertical aggregation factor) or three integers (when also aggregating over layers).
aggregateFunction	= colMeans, function used to aggregate values. Function must support vectorization of column as input, like base::colMeans.

Value

a lower resolution array(same dimensions)
