spRbind-methods

rbind for spatial objects

spRbind provides rbind-like methods for Spatial*DataFrame objects

Note

In addition to the spRbind-methods, there are also rbind-methods for Spatial* objects. The differences are:

1. spRbind-methods can bind 2 objects, whereas rbind-methods can bind multiple object

2. some rbind can accept objects with duplicated IDs, for all spRbind-methods these have to be modified explicitly, e.g. by calling spChFIDs-methods

Methods

obj = "SpatialPoints", x = "SpatialPoints"

rbind two SpatialPoints objects

obj = "SpatialPointsDataFrame", x = "SpatialPointsDataFrame"

rbind two SpatialPointsDataFrame objects

obj = "SpatialLines", x = "SpatialLines"

rbind two SpatialLines objects

obj = "SpatialLinesDataFrame", x = "SpatialLinesDataFrame"

rbind two SpatialLinesDataFrame objects

obj = "SpatialPolygons", x = "SpatialPolygons"

rbind two SpatialPolygons objects

obj = "SpatialPolygonsDataFrame", x = "SpatialPolygonsDataFrame"

rbind two SpatialPolygonsDataFrame objects
