download WorldClim variables. See www.worldclim.com.

Usage

envs_worldclim(bcRes, bcSel, mapCntr, doBrick = FALSE, logger = NULL)

Arguments

bcRes

numeric. Resolution of the climatic layers. Currently available resolutions are 0.5, 2.5 and 10.

bcSel

character. Vector with bionames to be selected.

mapCntr

numeric. Vector with longitude and latitude for a tile. Required for bcRes 0.5, for other resolutions world data will be downloaded.

doBrick

logical. Converts downloaded rasters to brick for faster processing.

logger

Stores all notification messages to be displayed in the Log Window of Wallace GUI. Insert the logger reactive list here for running in shiny, otherwise leave the default NULL.

Value

A rasterStack or a rasterBrick (if doBrick=TRUE) of downloaded worldclim rasters at the requested resolution.

Details

This function is called by the module envs to download WorldClim variables from www.worldclim.com. The variables to be downloaded are selected by the user with bcSel and the resolution with bcRes. It returns either a rasterStack or rasterBrick of selected variables with appropriate names for further analyses.
