Generate spatial distribution objects for species, genera or families

Usage

wcvp_distribution(
  taxon,
  taxon_rank = c("species", "genus", "family", "order", "higher"),
  native = TRUE,
  introduced = TRUE,
  extinct = TRUE,
  location_doubtful = TRUE,
  wcvp_names = NULL,
  wcvp_distributions = NULL
)

Arguments

taxon: Character. The taxon to be mapped. Must be provided.
taxon_rank: Character. One of "species", "genus", "family", "order" or "higher", giving the rank of the value in taxon.
native: Logical. Include native range? Defaults to TRUE.
introduced: Logical. Include introduced range? Defaults to TRUE.
extinct: Logical. Include extinct range? Defaults to TRUE.
location_doubtful: Logical. Include occurrences that are thought to be doubtful? Defaults to TRUE.
wcvp_names: A data frame of taxonomic names from WCVP version 7 or later. If NULL (the default), names will be loaded from rWCVPdata::wcvp_names.
wcvp_distributions: A data frame of distributions from WCVP version 7 or later. If NULL (the default), distributions will be loaded from rWCVPdata::wcvp_names.

Value

Simple features (sf) data frame containing the range polygon/s of the taxon.

Details

Where taxon_rank is higher than species, the distribution of the whole group will be returned, not individual species within that group. This also applies when toggling options - for example, introduced occurrences will only be included if they are outside the native range, regardless of whether native=TRUE or native=FALSE. To identify extinctions, introductions or doubtful occurrences within the native range, the wcvp_summary and wcvp_occ_mat functions can be used.

Examples

 # this example requires 'rWCVPdata'
if(requireNamespace("rWCVPdata")){
r <- wcvp_distribution("Callitris", taxon_rank = "genus")
p <- wcvp_distribution_map(r)
p
}
