...geoR package. I imported points from GRASS("zn", after converted to geodata "zn_geo"), the border "zn_border" and a raster mask. Then i interpolated the points by kriging and created a raster image. Now, i need export this image back to GRASS to use it in the module r.mapcalc. I can't do it. I tried use writeRAST6, but it returns a message: "tentativa de obter um slot "data" de um objeto cuja classe ("kriging") n?o ? um objeto S4" or "attempt to obtain a slot from an object whose class ("kriging") is not a S4 object&quot...

.... What do those coefficients actually mean ("The orthogonal polynomial is summarized by the coefficients, which can be used to evaluate it via the three-term recursion...")? We created a GLM model with a poly() term and I'm trying to apply this model in another program (grass gis via mapcalc) without requiring the direct link with R if at all possible. We'd like to avoid making a lookup table if at all possible. Thanks! --j -- Jonathan A.

Is there any way to run an R script without running R? As an example, suppose I have a tcl/tk interface that asks for a number (in a GUI) and displays its factorial. Is there a way to invoke this script without invoking R? I'm using R 2.4.1 in GNU/Linux Fedora Core 4. Alberto Monteiro
