Plot COSEWIC IAO and EOO — cosewic

Creates a plot of COSEWIC ranges for illustration and checking.

cosewic_plot(
  ranges,
  points = NULL,
  grid = NULL,
  map = NULL,
  species_id = "species_id",
  title = ""
)

Arguments

ranges: List. Output of cosewic_ranges() with spatial = TRUE.
points: Data frame. Optional naturecounts data used to compute ranges. Raw data points will be added to the plot if provided.
grid: sf data frame. Optional grid over which to summarize IAO values (useful for species with many points over a broad distribution).
map: sf data frame. Optional base map over which to plot the values.
species_id: Character. Name of the column containing species identification.
title: Character. Optional title to add to the map. Can be a named by species vector to supply different titles for different species.

Value

ggplot2 map

Examples


r <- cosewic_ranges(bcch)
cosewic_plot(r)

cosewic_plot(r, points = bcch)

cosewic_plot(r, grid = grid_canada(50), map = map_canada(), 
             title = "Black-capped chickadees")

             
m <- rbind(bcch, hofi)
r <- cosewic_ranges(m)
cosewic_plot(r)
#> $`14280`

#> 
#> $`20350`

#> 
cosewic_plot(r, points = m)
#> $`14280`

#> 
#> $`20350`

p <- cosewic_plot(r, grid = grid_canada(50), map = map_canada(),

                           "20350" = "House Finches"))
