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.
