Dear Members,
I am trying to fit a variogram model using fit.variogram function from the gstat package. The figure showing my experimental variogram can be seen here: https://i.stack.imgur.com/UZXw4.png My code line for this operation is: > c2.vgm.fit<-fit.variogram(c2.vgm.exp,vgm(nugget=0, > psill=400,model="Exp",range =40000),fit.method = 7) The system throws following error message: Error in switch(model, exponential = fit.exponential(v.object, c0 = nugget, : EXPR must be a length 1 vector Any help to know the cause of the error and avoiding it would be highly appreciated. Thank you very much Saubhagya Singh Rathore PhD Candidate Civil and Environmental Engineering Georgia Institute of Technology [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
