GSTAT

Hello list

In the gstat R package tutorial that accompanies the latest version of
GSTAT 0.9-29 it is pointed out that the function coordinates, when assigned
(on the left-hand side of an = or <- sign) promotes the data.frame meuse
into a SpatialPointsDataFrame.  Is there a function that does the opposite
ie. demote the same data set from SpatialPointsDataFrame back to a
data.frame?
