I have a little feature request inspired by the new geomapping function. Assume a spatial dataset including info from a shape file. Now we can easily produce maps, but to carry out spatial autocorrelation and spatial regression analysis we need a spatial weight matrix. Considering that all the coordinates info is included in the shape files, it would be nice to be able to recover the coordinates of the centroids of the units as an extra pair of variables. Then distance-based spatial weight matrices can be easily constructed by the user with his preferred formula (or using a contributed function taking the series with the coordinates as inputs - I can volunteer for that, it'd be at most 10 lines of code :-) ) bye Stefano ________________________________________________________________________ Stefano Fachin Professore Ordinario di Statistica Economica Dip. di Scienze Statistiche "Sapienza" Università di Roma P.le A.
