Plot cost

splnr_plot_cost() allows to plot cost within each planning units of a planning region in a customisable way using ggplot2. This function requires an sf object with a cost column and outputs a ggobject. It can be combined with the spatialplanr function splnr_gg_add().

Usage

splnr_plot_cost(
  Cost,
  Cost_name = "Cost",
  legendTitle = "Cost",
  paletteName = "YlGnBu",
  plotTitle = ""
)

Arguments

Cost

An sf object of cost for prioritizr

Cost_name

Name of the cost column

legendTitle

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

paletteName

A string (or number) for the color palette to use. Available palettes can be found at https://ggplot2.tidyverse.org/reference/scale_brewer.html.

plotTitle

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

Value

A ggplot object of the plot
