[R-sig-Geo] plotKML kml_layer.Raster problem

[Tomislav Hengl]

I would assume that the value column in the Raster object is somehow 
converted to "character" class.

If you could provide access to your data and code we can do a better job 
(it could be that there is also a bug in plotKML i.e. completely not 
your fault).

HTH,

T. Hengl
