Hi All, I have a question about producing keys in ssplot(). I've included reproducible code below. Here goes: I'd like to produce a key in ssplot that has both rectangles, points and lines. Unfortunately, when you include all of these symbols in one key, the produce a "staggered" look with

Dear all, I would like to use kriging to make spatial predictions based on a set of more than 300 points. My concern is that measurement errors vary over my points. I do have an estimator of this measurement errors but I don't know how to take it into account when estimating the semi-variogram and
