cbind for spatial objects

spCbind provides cbind-like methods for Spatial*DataFrame objects in addition to the $, [<- and [[<- methods already available.

Keywords
methods, spatial
Methods

obj = "SpatialPointsDataFrame", x = "data.frame"

cbind a data frame to the data slot of a SpatialPointsDataFrame object

obj = "SpatialPointsDataFrame", x = "vector"

cbind a vector to the data slot of a SpatialPointsDataFrame object

obj = "SpatialLinesDataFrame", x = "data.frame"

cbind a data frame to the data slot of a SpatialLinesDataFrame object; the data frame argument must have row names set to the Lines ID values, and should be re-ordered first by matching against a shared key column

obj = "SpatialLinesDataFrame", x = "vector"

cbind a vector to the data slot of a SpatialLinesDataFrame object

obj = "SpatialPolygonsDataFrame", x = "data.frame"

cbind a data frame to the data slot of a SpatialPolygonsDataFrame object; the data frame argument must have row names set to the Polygons ID values, and should be re-ordered first by matching against a shared key column

obj = "SpatialPolygonsDataFrame", x = "vector"

cbind a vector to the data slot of a SpatialPolygonsDataFrame object
