[R-sig-Geo] predicting values from model function

Dear List, I have fitted a spherical function to my variogram using "variofit(...)" from GeoR. Now I would like to predict some data with the function "predict(object,...)" from package stats. Does anyone know wether this works and if it does how to do it? Thanks a lot! Anna ___

[R-sig-Geo] self-starting non linear model

Hi List! I want to apply a selfstarting Michaelis-Menten-Model to my data: SSmicmen {stats} I use thist function in the following way: model<-nls(distance~SSmicmen(watercontent, Vm, K)) When I want to compute it I get the error message: Fehler

[R-sig-Geo] problems with loading geoR and sp

hey guys, i'm trying to work with CRAN package geoR. I installed it but loading it needs a shared library(sp). So i downloaded sp as well and installed it successfully. but when i load the library(sp) it says that it was not found and the warnings say it was constructed under r version and so o
