BIEN_ranges_species_bulk function

Extract range data for large numbers of species

BIEN_ranges_species_bulk downloads ranges for a large number of species using parallel processing.

BIEN_ranges_species_bulk(
  species = NULL,
  directory = NULL,
  batch_size = 1000,
  return_directory = TRUE,
  use_parallel = FALSE
)

Arguments

• species: A vector of species or NULL (the default). If NULL, all available ranges will be used.
• directory: The directory where range shapefiles will be stored. If NULL, a temporary directory will be used.
• batch_size: The number of ranges to download at once.
• return_directory: Should the directory be returned? Default is TRUE
• use_parallel: Logical. Should batches be downloaded in parallel? If set to TRUE, AND if parallel and foreach are available, parallel processing of downloads will use n-1 clusters.

Returns

Optionally, the directory to which the files were saved.

Note

This function may take a long time (hours) to run depending on the number of cores, download speed, etc.

## Not run:

#To download all BIEN ranges maps:
