4.3 Access values

Sometime, it is nice to be able to see the data values in a raster dataset or visualize the data for various kinds of checks. You can access the values stored in a SpatRaster object using values() function:

#--- terra::values ---#
values_from_rs <- values(IA_cdl_stack_sr) 

#--- take a look ---#
head(values_from_rs)

     Layer_1 Layer_1
[1,]       0       0
[2,]       0       0
[3,]       0       0
[4,]       0       0
[5,]       0       0
[6,]       0       0

The returned values come in a matrix form of two columns because we are getting values from a two-layer SpatRaster object (one column for each layer).
