# S4 method for class 'gridlayer,SpatExtent,missing'
x[i]

# S4 method for class 'gridlayer,ANY,ANY'
x[i] <- value

Arguments

x

(facelayer) The object to be subsetted.

i

(logical, numeric or SpatExtent) The subscript vector, or extent, specifying the faces that are used for subsetting. As in subset.

The replacement values.

The extraction methods return facelayer-class objects.

Details

All these methods are implementing direct replacement in the @values slot of a layer, depending on criteria used for subsetting.
