No sign of sp 0.9-27 at this end (Melbourne, Australia) yet. Interesting
that it should take so long.
I temporarily reset my repository to access the updates. Croatia already has
sp 0.9-28, along with gstat 0.9-53. (Does Tomislav receive special
treatment?)
Your example now works perfectly. Thank
That's right; my fault that I sent the email and updated the sp package
on CRAN almost at the same time. The new sp (0.9-27 would suffice)
should now have propagated to your mirror, simply update your sp package
again and it should work. Let me know if it doesn't.

Hello Edzer,
I was curious to run the example you provided (using the latest CRAN
versions of all packages), but as written the line
> idw.spdf = as(idw.out, "SpatialPolygonsDataFrame")
produces
Error in as(idw.out, "SpatialPolygonsDataFrame") : no method or default for

Dear all,
In continuation of this thread, I've spent some time looking at kriging
on the sphere, corrected some bugs, and need further help.
First of all, distances for covariances on the sphere were computed
incorrectly as well in gstat, so I hope not too many people have been
relying on th
Thanks for the bug report; indeed, distance computation for longlat data
variograms went wrong so far. I just uploaded a new gstat version to
/incoming on CRAN that seems to repair this bug.
Next thing I'm not 100% sure of is the direction selections for
directional variograms of longlat data.
Hello,
I am trying to use 'variogram' from the gstat package to compute an empirical
semivariogram for a dataset that spans the North American continent. I have
been unable to get gstat to calculate the great circle distances correctly.
For example, in the example below, the first two lines o
