Hi, When i do the next line it work fine:
fit.spherical(var, 0, 2.6, 250, type='c', iterations=10, tolerance=1e-06, echo=FALSE, plot.it=T, weighted=TRUE, delta=0.1, verbose=TRUE) But, i use the next and send one error: fit.variogram("spherical", var, nugget=0, sill=2.6, range=250, plot.it=TRUE, iterations=0) This is the error: Error in fit.variogram("spherical", var, nugget = 0, sill = 2.6, range = 250, : unused argument(s) (nugget = 0, sill = 2.6, range = 250, plot.it = TRUE, iterations = 0) any suggest?
