It serves as an "automated" method for doing spatial predictions. You can find the first testing version at http://www.fivaz.ch/grasper/index.html. For now, I provide a dump file you...

...re easy but not what R can do (additional to the "normal" statistics). I looked through the packages, but the enormous amount of packages makes it very difficult for me to decide which one is worth mentioning. I used only a small part of all R packages (mainly recommended packages and grasper) and would like to know which package for ecologist has to be mentioned. I would greatly appreciate if you can tell me which packages you think are very useful for ecolgical research in R e.g. vegan, ade4, ... thanks in advance, regards Martin

...m (in this example for GRASS module): Error: couldn't find function "GRASS.connect". In this specific case I tryed with GRASS running and without as well as launching R from inside GRASS but nothing works. The worst part is the tha very same happend with all the other packages, like GraspeR, geoR, akima, etc.... Well, I tryed to get something about that in the mailing list archives, but I found nothing up to now. Any one have any idea about where is the problem? (I guess it is sitting on my chair!) My system: Mandrake 9.1, R 1.7.1-1mdk, tcl/tk 8.3.3-21.mdk... Thnak you in advance!...

Hello, Apologies if this question has already arised, hope you can help me to the find the solution to this or point the place to look at. I have a multidimensional piece-wise regression linear problem, i.e. to find not only the regression coefficients for each "interval" but also the beginning and ends of the intervals. To simplify it to the one dimensional case and two intervals,
