Download bioclimatic data from Bioclim

This function is called by the cov_bioclim module and downloads bioclimatic data on from Bioclim via geodata. It returns a list of SpatRasters for the selected variables

cov_bioclim(shape, country_code, variables, async = FALSE)

Arguments

shape

sf. sf object containing the area of interest

country_code

vector. ISO3 code of the country or countries.

variables

vector. List of the bioclimatic variables to be returned. Options are: Mean temperature, Mean diurnal range, Isothermality, Temperature seasonality, Maximum temperature warmest month, Minimum temperature coldest month, Temperature range, Mean temperature wettest quarter, Mean temperature driest quarter, Mean temperature warmest quarter, Mean temperature coldest quarter, Total precipitation, Precipitation wettest month, Precipitation driest month, Precipitation seasonality, Precipitation wettest quarter, Precipitation driest quarter, Precipitation warmest quarter, Precipitation coldest quarter

async

logical. Whether or not the function is being used asynchronously

Value

a list of containing an item for each variable, either SpatRaster objects when async is FALSE or PackedSpatRaster objects when async is TRUE
