Dear Roger Bivand and Dan Putler, Currently I'm working on the spatial point data analysis using Kernel estimation (spatstat), Ripley's K function (spatstat) and space-time K function (splancs). My research is at the continental level and the region area includes Asia, Europe and Africa. The metho

Dear List, I'm working with Indoor Radon data and I've to try alternative spatial correlation measures than classical variogram, such as rodogram or madogram; here my questions: i) is there a package with routines able to compute this functions? ii) if not, how can I (if is it possible!) edit an

[R-sig-Geo] Could you add my 'Jenks' method to your classInt package?

2007-11-21 Thread Hisaji ONO
Hello. I've tried to port Java code for Jenks optimization classification method "natural break" to R, although far from smart coding. My java code was ported Jenks's Basic code and I checked these results compared to results of ArcView 3.x. Jenks method derived from Fischer, but seems to be
