load_layers {sdmpredictors}

Load layers

Description

Method to load rasters from disk or from the internet. By default a RasterStack is returned but this is only possible When all rasters have the same spatial extent and resolution.

Usage

load_layers(layercodes, equalarea=FALSE, rasterstack=TRUE, 
  datadir=NULL)

Arguments

layercodes

character vector or dataframe. Layer_codes of the layers to be loaded or dataframe with a "layer_code" column.

equalarea

logical. If TRUE then layers are loaded with a Behrmann cylindrical equal-area projection (equalareaproj), otherwise unprojected (lonlatproj). Default is FALSE.

rasterstack

logical. If TRUE (default value) then the result is a stack otherwise a list of rasters is returned.

datadir

character. Directory where you want to store the data. If NULL is passed (default) then the sdmpredictors_datadir option is read. To set this run options(sdmpredictors_datadir="<your preferred directory>") in every session or add it to your .RProfile.

Value

RasterStack or list of raster
