Dear list,

I have a polygon that I converted to raster (kudos to polygonsToRaster()). I
would like to assign values (through a custom function) to cells within this
polygon (now as raster). Roughly speaking, cell value will depend on its
distance from the central cell (polygon centroid). How would you go about
doing this? Is there a more efficient way of doing this, or will I have to
hard code it, cell by cell?

Cheers,
Roman
