Examples

# load data data(sim_pu_raster, sim_pu_zones_stack, sim_features, sim_features_zones) # create problem with one zone p1 <- problem(sim_pu_raster, sim_features) %>% add_min_set_objective() %>% add_relative_targets(0.2) %>% add_binary_decisions() # print number of planning units print(number_of_planning_units(p1))
#> [1] 90
# print number of total units print(number_of_total_units(p1))
#> [1] 100
# create problem with multiple zones p2 <- problem(sim_pu_zones_stack, sim_features_zones) %>% add_min_set_objective() %>% add_relative_targets(matrix(0.2, ncol = 3, nrow = 5)) %>% add_binary_decisions() # print number of planning units print(number_of_planning_units(p2))
#> [1] 90
# print number of total units print(number_of_total_units(p2))
#> [1] 100
