Hi Antonio, I haven't seen a reply to your question yet, so I'll make a try. I'm having the same issue myself. What I've ended up doing is replacing NA's with a big negative value, define "levels" as one color for negative values, and a regular scale above. This gives a fairly good separation between what areas contain data, and what doesn't. To make NA's black, I suppose one would have to define your own colour.palette, but I haven't looked into it. Hope this helps, and let me know if you've found a better solution!
