Virtual class which contains the four classes
RFspatialGridDataFrame
(data on a full grid and $space-time-dimension \ge
2$),
RFspatialPointsDataFrame
(data not on a grid and $space-time-dimension \ge
2$),
RFgridDataFrame
(data on a full grid and $space-time-dimension = 1$),
RFpointsDataFrame
(data not on a grid spaced and $space-time-dimension = 1$)
Arguments
Objects from the Class
are never to be generated; only derived classes can be meaningful
Warning
this class is not useful in itself, but the above
mentioned classes in this package derive from it
