Dear, I have XYZ data available in a MySQL database. I get it out, can plot the data with the plot() function, load it into a geoR datastructure. But what I actually would like to do is a simple contouring of the data based on a no Kriging interpolation such as TIN based. I know the first thing I shold do is interpolate a full matrix for the region I have my points for, then contour should do its work. Any idea which function can be used for XYZ interpolations, maybe/hopefully based on a Delaunay triangulation in combination with linear or spline interpolation. Is there a package that allows me to do this?

It's an example for S-PLUS, so you might need some modifications. geography.uoregon.edu/courses/geog414f01/lectures/lec10.htm I hope this would help you.
