Supported aggregation rules — GEOSCALE

Each rule defines behaviour in both directions. Direction is taken from the geoframe ranks, so aggregation and disaggregation are one operation:

Usage

GEOSCALE_RULES

A character vector of length 5.

sum: Up: sum. Down: split proportionally to the weight. For extensive quantities (capacity, demand, area, population).
weighted_mean: Up: weight-weighted mean. Down: copy unchanged. For intensive quantities (efficiency, price, capacity factor).
mean: Up: unweighted mean. Down: copy unchanged.
copy: Up: the common value, erroring if it is not constant. Down: copy unchanged. For region-invariant scalars.
sd: Up: standard deviation over the atoms (aggregation only; going down it degenerates to NA for single-atom groups).
