SpatialArray-class: Virtual Array of Vector Spatial data

Description

Array template for Spatial object

Value

A SpatialStack class object.

Arguments

stack

A SpatialStack class object.

index

A vector, matrix or array type object. Includes either the indices of layers in the stack, or their names.

dim

A numeric vector. Same as for array, creates proxy procedurally.

Details

The class implements structures to organize Spatial objects that have the same CRS. Subsetting rules were defined using the proxy object in the index slot. See examples for implementations.

The class has two slots: stack: SpatialStack, the actual data. index: A proxy object that represents the organization of the layers.

Examples

# data import
  data(dems)
  st <-dems@stack
  ind <- 1:nlayers(st)
  names(ind) <- letters[1:length(ind)]
  ra<- RasterArray(stack=st, index=ind)
