Allocate a Management System to a Surface Fraction

Source: R/rfcm--allocate.R
allocate_surface.Rd

Assigns a new management system to a fraction of surface area by selecting clusters that match given spatial and structural criteria.

Usage

allocate_surface(
  map,
  system,
  target_fraction,
  ditches = 1:26,
  field_type = c("both", "regular", "tancat")
)

Arguments

map

[erahumed_cluster_map]
A cluster map created with new_cluster_map() or default_cluster_map().

system

[erahumed_management_system]
A management system to assign, created with new_management_system() or helper functions such as bomba() or clearfield().

target_fraction

[numeric(1)]
The fraction of total surface area to allocate to the given system. Must be a number between 0 and 1.

ditches

[integer]
A vector of ditch IDs where candidate clusters will be selected from. Defaults to all ditches (1:26).

field_type

[character(1)]
Type of field to consider when selecting clusters. Must be one of:

  • "regular" – only regular fields

  • "tancat" – only tancats

  • "both" – all field types (default)

Value

An updated erahumed_cluster_map object with the new system allocated to selected clusters.

Details

This function randomly selects clusters matching the specified ditches and field_type until the cumulative surface area of selected clusters reaches the target_fraction. The new management system is added to the internal list and assigned a unique ID within the map.

If no eligible clusters remain before reaching the target fraction, the function will return early with a partial allocation.

Examples

map <- new_cluster_map(jsendra())
map <- allocate_surface(map, bomba(), target_fraction = 0.1, field_type = "tancat")
