envs_worldclim: envs_worldclim Obtain WorldClim variables

In wallace: A Modular Platform for Reproducible Modeling of Species Niches and Distributions

envs_worldclim Obtain WorldClim variables

Description

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.

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.

Value

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