Arguments

m
n by 3 matrix with spatial data
iter
this argument is put forward to the optimization routine
tolerance
this argument is put forward to the optimization routine
trace
if set to values higher than 1 some debug messages are given
loo
if set to TRUE, leave-one-out residuals are clculated

Value

a variogram object
