Just a couple of comments. 1.) R has been my main programming language for a number of years now. I am involved with a mix of enivronmental tasks--statsitcs, geostatsitcs, site characterization, fate and transport, risk assessment. It is powerful, accessible and one can be productive very quickly. So much high-level functionality is already built into it, it is multi-platform and has production quality graphics. Oh yes, database connectivity is supurb.
I have not grown comfortable the the geostats packages--certainly I have used parts of several of them. Sometime back noticed different variograms from one of the packages--sorry can't remember--and GEOEAS, It was nothing major, just one used the mid-point distance in the lags and the other used the average lag difference. Looking--quickly I admit--at the R-package's documentation it was clear that no discussion was there. That left me wondering how many other 'little decisions' are wired into the package(s). Still I use them, but with caution. A standard R list response applies -- look at the code ;o) The point here is that --- Isobel Clark <[EMAIL PROTECTED]> wrote: > Have you looked at R?
