  projection = 4326,
  scenario = "present",
  ...
)

Value

Range maps for specified species.

Arguments

species

A single species or a vector of species.

directory

Directory that range maps should be saved in.

default_only

Logical. Should only default ranges be included? Default is TRUE.

matched

Return a list of taxa that were downloaded. Default is TRUE.

match_names_only

Check for range maps for the taxa specified without downloading range maps. Default is FALSE.

include_id

Logical. Should the range_id be appended to the file name? Needed to save multiple maps per species.

projection

Numeric. What projection should maps be returned in? 4326 (default) or 3857

scenario

Examples

# \donttest{

library(maps) #a convenient source of maps
library(sf)

species_vector <- c("Abies_lasiocarpa","Abies_amabilis")

#check whether the species are available
OpenRange_species(species_vector,match_names_only = TRUE)

#Create a temp directory
temp_dir <- file.path(tempdir(), "BIEN_temp")

#Download ranges
OpenRange_species(species = species_vector,
                 directory = temp_dir)#saves ranges to a temporary directory

#Reading files

Abies_poly <- st_read(dsn = temp_dir,
                     layer = "Abies_amabilis_117684")

#Plotting files
plot(Abies_poly[,1])#plots the range, but doesn't mean much without any reference
map('world', fill = TRUE, col = "grey")#plots a world map (WGS84 projection), in grey
plot(Abies_poly,col="forest green",add=TRUE) #adds the range of Abies lasiocarpa to the map
