[R-sig-Geo] Customized cost distance function ?

[Jean-Paul Kibambe Lubamba]

Hello list,

I want to compute a cost distance function (or even an euclidean 
distance), from a polyline object.

Instead of closest cells (to polylines) of the resulting cost distance 
raster having a value of 0, I would want them to pick up an attribute 
value of the related line object. Their neighborhood cells will have  
values  based on the cost distance or euclidean distance algorithm. 
Roughly speaking, I do not want "origin" cells of the cost distance 
raster to have a value of zero but a value from an attribute of the 
nearest line object.
 
Does anyone have a suggestion ?

Any help is welcome... Thanks in advance !
