! Have you looked at spsurvey? It may not provide what you need, but checking it would probably help you see whether there is anything meeting your needs. Otherwise you might need to stratify first on your covariates. Roger Regards, Jin Jin Li, PhD

[R-sig-Geo] Spatial sampling design using information more than spatial coordinates [SEC=UNCLASSIFIED]

my own function for it, I would like to confirm if I have missed some other functions that are available for it in R. Any suggestions and advice? Thanks in advance! Regards, Jin Jin Li, PhD Spatial Modeller/Computational Statistician | National Earth and Marine Observations Group

Re: [R-sig-Geo] [DKIM] Re: spatial modelling projection question [SEC=UNCLASSIFIED]

The effects of spatial reference systems on the predictive accuracy have been preliminarily tested recently. Please see W. Jiang, J. Li. 2013. Are Spatial Modelling Methods Sensitive to Spatial Reference Systems for Predicting Marine Environmental Variables? In: International Congress on
