filled.contour and NA's
Hi Gustaf
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.
How to define 'levels' as one color for negative values and a regular scale above? I don't know how the syntax within the filled.contour function shoul be. BR Antonio
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! Best, Gustaf Rydevik
