Create a RasterStack from a list of rasters and names

raster_stack.Rd

This function creates a `SpatRaster` stack from a list of rasters and assigns unique names to each layer.

Usage

raster_stack(raster_list, names = NULL)

Arguments

raster_list

A list of `SpatRaster` objects or file paths to raster files.

names

A character vector of unique names for each raster layer in the stack.

Value

A SpatRaster object with named layers.

Details

The function checks that the length of `raster_list` matches the length of `names`, and that all names are unique. If not, it stops with an error.

Examples

# Example with terra rasters
library(terra)
#> terra 1.8.93
r1 <- rast(nrows=10, ncols=10, vals=1:100)
r2 <- rast(nrows=10, ncols=10, vals=101:200)
raster_stack(list(r1, r2), c("layer1", "layer2"))

#> size        : 10, 10, 2  (nrow, ncol, nlyr)
#> resolution  : 36, 18  (x, y)
#> extent      : -180, 180, -90, 90  (xmin, xmax, ymin, ymax)
#> coord. ref. : lon/lat WGS 84 (CRS84) (OGC:CRS84) 
#> source(s)   : memory
#> names       : layer1, layer2 
#> min values  :      1,    101 
#> max values  :    100,    200
