Dear list/ Dr. Bivand, is it possible to plot spplot if there is no Longitude and Latitude in my data? (i.e. asking R to find latitude and longitude itself, is there any way to do that)? Milan

Milan, That depends on what there is in your data. Please provide a clear description of the relevant variables you have (coordinates in another reference system? textual geo-references?); and perhaps add a "summary(x)". Robert

To use spplot: Your data must have coordinates. The coordinates do not have to be longitude and latitude. You have to tell R where to find the coordinates, it cannot find them for you. Telling R where to find the coordinates might be very easy, depending on what is already in your data, or where it came from and how you loaded it into R. -Don
