Prepare distribution maps and summary for Invasive Alien Species (IAS)

Source: R/DWF_IAS_Distribution.R
IAS_Distribution.Rd

This function processes and analyzes distribution data for Invasive Alien Species (IAS) from multiple sources (GBIF, EASIN, and eLTER). It generates presence-absence maps, summarizes distribution data per country and biogeographical region, and outputs results as tif, RData, and tibble formats.

Usage

IAS_Distribution(
  Species,
  FromHPC = TRUE,
  EnvFile = ".env",
  Verbose = FALSE,
  Overwrite = FALSE
)

Arguments

Species

Character. Name of the species to analyze.

FromHPC

Logical indicating whether the work is being done from HPC, to adjust file paths accordingly. Default: TRUE.

EnvFile

Character. The path to the environment file containing variables required by the function. Default is ".env".

Verbose

Logical. If TRUE, detailed output is printed. Default is FALSE.

Overwrite

Logical. If TRUE, the function will overwrite existing files (default: FALSE).

Value

A tibble containing species distribution information, including the number of presence grid cells, presence by data provider, and summary statistics for biogeographical regions.

Note

  • This function is not intended to be used directly by the user or in the IAS-pDT, but only used inside the IAS_Process function.

  • The function returns two sets of presence-absence maps: 1) at the European scale giving the data in the three data sources; and 2) the same maps, but with assigning grid cells from countries with only cultivated or casual observations.
