Error autoKrige
Could you please verify (with zerodist) whether you have duplicate observations in your data set (i.e., multiple observations sharing a common spatial location)?

Dear all,
I want to do 10 kriging maps with packages automap.So ,I use
autofitvariogram for fitting the experimental variogram then I use the
command autokrige.
I have this error:
In getModel(initial_sill - initial_nugget, m, initial_range, ... :
An error has occured during variogram fitting. Used:
nugget: 0
model: Ste
psill: 1.13727235894792
range: 6.5336666581637
kappa: 10
as initial guess. This particular variogram fit is not taken into account.
Gstat error:
Error in fit.variogram(experimental_variogram, model = vgm(psill = psill, :
fit.method 7 will not work with zero distance semivariances; use another
fit.method value
I change the option fit.method =7 by differents number betwen 1 and 6 but I
have always this error.
Do you can help me
