Function to download GADM data for a country at a specific level

Description

This function downloads the GADM shapefile for a country (https://gadm.org/data.html). If the file is already on disk it will not perform the download. The function can check if better resolutions are available in disk.

Usage

getGADM(cod, level = 4, type = "sf", best = FALSE, destfolder = "GADM", ...)

Arguments

cod	Three letter ISO code for the country.
level	Administrative level. 0 stands for country and 1 to 4 are the successive successive nested levels. Not every country has the same depth and the nestedness is sequential. This means a country with two levels has levels 0 and 1, not 0 and 4, and that units such as states or municipalities can correspond to different levels depending on the country
type	The class of spatial object to be downloaded. Defaults to "sf" but can be set to "sp"
best	TRUE Checks if finer resolutions are available and avoids downloading data at coarser resolutions. Defaults to TRUE (will not download coarser resolution files)
destfolder	The destination folder
...	Options for download.file()
