Hello everybody! I have a problem, which I'm trying to solve. I have two Krig-fits: kr_one and kr_two; both use x and y and additional either A (kr_one) or B (kr_two): kr_one <- with(1, Krig(cbind(x,y), A)) kr_two <- with(1, Krig(cbind(x,y), B)) I can view the 3d-plane using: image(predict.surface(kr_one)) My question is how do I manage to ask R to give me that pair of x and y that corresponds to a given pair of A and B. There are many pairs of x and y in kr_one that correspond to A; and there are also many pairs of x and y that correspond to B in kr_two. But there's is only one pair of x and y that corresponds to both, A and B. I want to find exactly this pair. Some help on this would be very appreciated!
