Description

get_rasters Loads rasters from directory and returns them in an organized list of specified scenarios.

Usage

get_rasters(
  var = NULL,
  scenario = NULL,
  raster_path = NULL,
  ext = c(-180, 180, -60, 90),
  coord_col = c("Lon", "Lat"),
  margin = 0,
  separator = "_"
)

Arguments

var	character. Names of variables to be loaded.
scenario	character. Names of scenarios for the variables.
raster_path	character. Path to folder with raster files. See writeFormats for supported formats
ext	numeric, data. frame or Extent object. Extent to crop rasters.
coord_col	character. Names of columns containing Longitude and Latitude.
margin	numeric. Additional distance to be added to margin of extent, in degrees.
separator	character. Character that separates variable names and scenario names.

Value

Returns a list of raster stacks for the variables required, organized by year/scenario combination.

Examples

## Not run: 
# replace rasterpath with the directory on your computer containing worldclim data

Fulanus_Ecorasters_present <-
  get_rasters(
    var = c('prec', 'tmin', 'tmax'),
    scenario = 'present',
    raster_path = "C:/Users/gabri/Dropbox/Mapinguari/global_grids_10_minutes",
    ext = FulanusDistribution[c(2,3)],
    margin = 5)

## End(Not run)
