In sjevelazco/flexsdm: Tools for Data Preparation, Fitting, Prediction, Evaluation, and Post-Processing of Species Distribution Models

Transform a spatial partition layer to the same spatial properties as environmental variables

Description

Transform a spatial partition layer to the same spatial properties as environmental variables

Usage

get_block(env_layer, best_grid)

Arguments

env_layer	SpatRaster object with some environmental variables used in the block_partition or band_partition function. Function always will select the first layer
best_grid	SpatRaster object returned by block_partition or band_partition

Details

Transform a layer originating from the function block_partition or band_partition to the same spatial properties as the environmental variables

Value

A SpatRaster layer with the same resolution and extent as the environmental variables

Examples

## Not run: 
require(dplyr)
require(terra)
data(spp)
f <- system.file("external/somevar.tif", package = "flexsdm")
somevar <- terra::rast(f)

# Example for a single species
single_spp <- spp %>% dplyr::filter(species == "sp3")

part <- part_sblock(
  env_layer = somevar,
  data = single_spp,
  x = "x",
  y = "y",
  pr_ab = "pr_ab",
  min_res_mult = 100,
  max_res_mult = 500,
  num_grids = 10,
  min_occ = 5,
  n_part = 2
)

grid_env <- get_block(env_layer = somevar, best_grid = part$grid)
grid_env
part$grid

plot(part$grid)
plot(grid_env)
