add_connected_constraints: Add connected constraints

In prioritizr/prioritizrutils: Utilities for prioritizr

Description

Add constraints to a conservation problem to ensure that all selected planning units are spatially connected to each other.

Usage

add_connected_constraints(x, ...)

Arguments

x	ConservationProblem-class object.
...	arguments passed to connected_matrix.

Value

ConservationProblem-class object with the constraint added to it.

See Also

constraints for all the available constraints.

Examples

# create basic problem
p1 <- problem(sim_pu_raster, sim_features) %>%
  add_min_set_objective() %>%
  add_relative_targets(0.2)

# create problem with added connected constraints
p2 <- p1 %>% add_connected_constraints()


# solve problems
s <- stack(solve(p1), solve(p2))

# plot solutions
plot(s, main=c("basic solution", "connected solution"))
