Coercion with 'as' seems to fail for me:
rb=bbox(r) rb
min max x -2.840466 -2.342137 y 54.042700 54.339724
as(rb,"Spatial")
Error in as(rb, "Spatial") : no method or default for coercing "matrix" to "Spatial" but using Spatial() works: plot(Spatial(rb))
Would plot(as(rb, "Spatial")) work - the object needs to be just "Spatial" to just set up the plot device? I didn't check what was what carefully enough. Roger
despite the warning about Spatial being an abstract class...
which drops all the unnecessary stuff. I wasn't sure what was needed, either. It could be an output file with the data reshaped to "wide" from "long", but this is just another guess.
Texas may be awake now, but I think it might be a holiday in the USA... Barry
