Can R perform matrix algebra between ascii converted Esri grids? I'm
convinced that its trivial.

 

The question is a little more complex (from my point of view and
inexperience): I'm interested in perform cost surface and distance surface
analysis avoiding ArcGIS tools. Maybe R can deal with grid formatted as
matrices...

 

Maybe R could call FWtools to perform all calculations iteratively...
