Collect the regions an object operates in

Source: R/get_region.R
get_region.Rd

Generic, reflective accessor that walks every slot of an S4 model object (except misc) and gathers the regions it refers to. Regions are read from:

  • any atomic slot named region, src, or dst, and

  • the region, src, and dst columns of any data.frame slot.

Usage

get_region(obj)

Arguments

obj

a model object (S4) such as technology, storage, trade, import, or export.

Value

a character vector of region labels (possibly empty).

Details

The result is the set of unique, non-missing, non-empty region labels. The function is intentionally schema-agnostic so it keeps working as region information is added to classes that do not yet carry an explicit @region slot (e.g. import / export).
