Plot cost overlay

splnr_plot_costOverlay() allows to plot the cost of each planning units of a planning region on top of the solution of a conservation problem created with prioritizr in a customisable way using ggplot2. This function requires a solution as an sf object with a column called solution_1 as well as a cost column and outputs a ggobject. It can be combined with the spatialplanr function splnr_gg_add().

Usage

splnr_plot_costOverlay(
  soln,
  Cost = NA,
  Cost_name = "Cost",
  legendTitle = "Cost",
  plotTitle = "Solution overlaid with cost"
)

Arguments

soln

The prioritizr solution

Cost

An sf object of cost for prioritizr.In case prioritizrsolution does not contain cost, alternative cost object has to be provided here that was used to generate solution (default: NA).

Cost_name

Name of the cost column

legendTitle

A character value for the title of the legend. Can be empty ("").

plotTitle

A character value for the title of the plot. Can be empty ("").

Value

A ggplot object of the plot

Examples

dat_problem <- prioritizr::problem(dat_species_bin %>% dplyr::mutate(Cost = runif(n = dim(.)[[1]])),
  features = c("Spp1", "Spp2", "Spp3", "Spp4", "Spp5"),
  cost_column = "Cost"
) %>%
  prioritizr::add_min_set_objective() %>%
  prioritizr::add_relative_targets(0.3) %>%
  prioritizr::add_binary_decisions() %>%
  prioritizr::add_default_solver(verbose = FALSE)

dat_soln <- dat_problem %>%
  prioritizr::solve.ConservationProblem()

splnr_plot_costOverlay(soln = dat_soln)
