[R-sig-Geo] GSTAT - singular in meters not km

[Zev Ross]

Hi All,

I'm fitting variograms in GSTAT with fit.variogram and I was surprised 
to find that all my fits were singular. I experimented with converting 
the data to unprojected data (decimal degrees) and with dividing my X 
and Y coordinates, which are in meters, by 1000 (to get KM). In both 
cases the fitting procedure worked with no singularity. Based on the 
numbers of pairs the bins appeared to be about the same so it appears to 
be a matter of the coordinates themselves.

I'd prefer not to have to convert the coordinates back and forth between 
meters and KM, any suggestions?

Zev
