Procedural example structure to demonstrate the capabilities of the 'RasterArray' class

Binary versions of SpatRaster-class objects are problematic, this function is used to instantiate a RasterArray example.

Usage

rastex()

Value

A two-dimensional RasterArray-class object, with three rows and four columns.

Examples

# create example
example <- rastex()

# subset - single bracket
example['b']
#> class       : SpatRaster 
#> dimensions  : 180, 360, 1  (nrow, ncol, nlyr)
#> resolution  : 1, 1  (x, y)
#> extent      : -180, 180, -90, 90  (xmin, xmax, ymin, ymax)
#> coord. ref. : lon/lat WGS 84 
#> source(s)   : memory
#> name        : layer_2 
#> min value   :       2 
#> max value   :   64801
