Dear Reasearchers I am try to use "smooth.spline" with a X,Y,Z points file
smooth.spline(x, y = NULL, w = NULL, df, spar = NULL, cv = FALSE, all.knots = FALSE, nknots = NULL, keep.data = TRUE, df.offset = 0, penalty = 1, control.spar = list()) where: xa vector giving the values of the predictor variable, or a list or a two-column matrix specifying x and y.yresponses. If y is missing, the responses are assumed to be specified by x. mydata str(mydata) 'data.frame': 135660 obs. of 3 variables: $ X: num 1666025 1666025 1666025 1666026 1666026 ... $ Y: num 7114025 7114026 7114028 7114026 7114027 ... $ H: num 270 270 270 270 270 ... myxy <- as.matrix(data.frame(mydata$X,mydata$Y)) myvalue <- list(mydata$H) cc <- smooth.spline(myxy,myvalue) Errore in xy.coords(x, y) : 'x' and 'y' lengths differ I have this type of error. I tried the solutions inside the mail-list and help but I can not processing smooth.spline thanks and sorry for the disturb gianni [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
