Both Canada and Norway - especially including Spitzbergen - suffer from
Roger's solution makes sense to me.
The sinusoidal does have the appearance of pinching poleward, a
consequence of allocating equal area by spacing equally in both x and y.
Also the Lambert cylindrical sent in before should have had standard
parallels set to +/- 30, i.e.,

Canada looks pinched in this projection. S. Am is perfect.

perhaps use
spplot(OK_pred[1], ...)
which would be more or less short for
levelplot(var1.pred~x+y, as.data.frame(OK_pred), aspect = "iso", ...)

For preview graphics and for large areas such as continents, large
countries, hemispheres, or the whole earth, spherical projections are
often adequate. I can provide some of the ones I have used. For
detailed work at sites and small areas, ellipsoidal projections such as
UTM are usually used, an
hello
why does levelplot function give an error
OK_pred <- krige(z~1,el4, newdata=mask_SG, model=efitted)
levelplot(var1.pred ~ x + y , OK_pred , aspect = mapasp(OK_pred), main =
"ordinary kriging predictions")
Error in eval(expr, envir, enclos) : invalid 'envir' argument

hello
I want to learn about how I can interpret a variogram and its values
(sill, nugget, etc)
can you supply me any links and addresses in which these subjects are
explained ?
regards
