Dear geoUseRs,


I have a semi-variogram with a clear periodic curve.
I tried to fit a model coming from the vgm function (gstat) but it (the
fit.variogram function) does not achieve to fit correct parameters because
there is a phase-shift between the wave curve that I obtained with vgm using
the model "Per" and my semi-variogram.

Is there a way to change the phase of this curve ?

Thanks !

Arnaud
