Function to add additional data to an existing plot

elsar_plot_extra_data() allows to add extra data to an existing ggplot or tmap plot, e.g. protected areas generated with make_protected_areas(). Function idea taken from spatialplanr package.

Uso

elsar_plot_extra_data(
  plot_type = "ggplot",
  include_pas = NULL,
  pas_look = "contours",
  alpha_pa = 0.5,
  color_pa = "black",
  legend_pa = "",
  label_pa = "PAs"
)

Argumentos

plot_type

A character denoting whether "ggplot" or "tmap" is being used. Needs to match the main plot

include_pas

An sf object with the PAs in the area, e.g. created with the make_protected_areas() function with the setting return_sf = TRUE.

pas_look

A character denoting whether to show "contours" or "area" of PAs.

alpha_pa

A value (0-1) for the opacity of the locked in areas when plotted on top of other plots.

color_pa

A color value for the locked in areas.

legend_pa

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

label_pa

The legend label of the locked in area (e.g. MPAs)

Valor

For ggplot returns a list that can simply be added to a ggplot, e.g. elsar_plot_static_raster_c().

boundary_proj <- make_boundary(
  boundary_in = boundary_dat,
  iso3 = "NPL",

pus <- make_planning_units(
  boundary_proj = boundary_proj,
  pu_size = NULL,
  pu_threshold = 8.5e5,
  limit_to_mainland = FALSE
)
wad_dat <- get_wad_data()

wadOut <- make_normalised_raster(
  raster_in = wad_dat,
  pus = pus,
  iso3 = "NPL"
