[R-sig-Geo] Can anyone recommend an areal interpolation package?

[Jon Olav Skoien]

Hi Juta,

You could try with the rtop package which also does area to area 
interpolation, but with a different method than the one used by ArcGIS. 
It was developed for a rather different use case (hydrological variables 
along stream networks), but should also be able to deal with data of the 
type you describe.

Best wishes,
Jon
