Hi,
In gstat and  package the fit.variogram.reml function provided for
RMLE method to  estimation of variogram parameters. This function only
estimate nugget and sill and range parameter is fix.

for example:

v.rml<-fit.variogram.reml(rate~1,data,model =vgm(200000,"Sph",95241.99,0))
v.rml
  model     psill    range
1   Nug -1711.462     0.00
2   Sph  3431.108 95241.99

How can I set the best range value?
If  exist a way to estimate range like( fit.ranges = TRUE) in
fit.variogram function?

Best,
