Dear list members,

I am doing a kriging and I got this error message.

 > rich.kriged = krige(N~1, rich, r, model = rich.fit)
Error en proj4string(newdata) :
   proj4string only works for class(es extending) Spatial

"rich" is SpatialPointsDataFrame
"r" is a projected raster

Any help will be appreciatedr?

Best,

Manuel
