Spatial sampling design using information more than spatial coordinates [SEC=UNCLASSIFIED]

Hi All, I need to consider both spatial information and another variable (e.g. elevation, soil type) in a sampling design. It seems the available libraries (e.g. sp and spcosa) in R for spatial sampling design are unable to handle it. Please correct me if I am wrong. Before I start to develop 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!
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
