I have a Spatial Point Data Frame(spdf) ( and separately I also have primary road shapefile and Spatial polygon on a county.)
What I am trying to do is that making this spdf to raster stack or raster brick so I can make prediction on it. I first convert it to a data.frame y20081 then I used.

any ideas?
