I agree with Thomas that seeing a warning is a worry. If Paul's automap
takes care of singular fits by discarding them, it should try to hide
the warning for the user, because otherwise it will worry them. I see
that the warning is issued by the C code in gstat, and will rethink
about how a wra
Hi Thomas,
The automatic fitting procedure checks a range of possible variogram
models, including Spherical, Exponential, Gaussian and Matern models.
Each of these models could lead to a singular model fit. The fitting
function in gstat (fit.variogram) says the following on singular model fits:
Paul,
This is outstanding; thank you very much! BTW, I noticed that when I run
your example that I get:
Warning: singular model in variogram fit
…actually, 2 such warnings with the OK example, and 1 with the UK
example. Are you seeing these too? Otherwise, the results look fine…
Thanks again
Dear r-sig-geo,
In the course of my PhD I have written a R package that performs
automatic interpolation (kriging) and might be interesting for other
people. I work on real-time automatic interpolation of radioactivity
levels. It depends heavily on the gstat pacakge written by Edzer
