Vector data in the same CRS organized into a vector.
A SpatialStack class object.
A list of Spatial objects or a character vector of file names identifying items for readOGR, in case the rgdal package is installed..
A CRS-class object.
A logical value. Same as for array, creates proxy procedurally.
The class implements a stack of vector data that mimic RasterStack-class objects, only with vector data.
Classes, such as link[sp]{SpatialPoints}, link[sp]{SpatialPointsDataFrame}, link[sp]{SpatialLines}, link[sp]{SpatialLinesDataFrame},
link[sp]{SpatialPolygons} and link[sp]{SpatialPolygonsDataFrame} can be concatenated to a vector/list, where elements can be accessed
using list-type subsetting. The only restriction is that the items must share the same CRS.
The class has two slots:
Spatials: List of Spatial items.
CRS: The coordinate reference system (CRS).
bbox: The bounding box of all items.
