Hi- There is a public doman geostatistics package used in the minieral industry called GSLIB and I would like to use it from R. However it is fortran (but portable and easy to compile on windows and linux)and has its own file format and control file format. It seems easiest to write an r function to dump r data to an ascii file, build a control file in ascii; call the GSLIB program with

I wonder what is the default value for the argument 'cutoff' when not specified in the variogram.formula function of gstat.

Can Edzer tell us about it? All the

List: I have 2 related questions: (1) first I have x-y-z data, where x & y are the geographic locations of point values, z. I need to perform a normal score transform on the z-values and maintain their geographic location. So, how do I go from columns x-y-z to x-y-z-t (or x-y-t), where the t-values are the normal score transforms of the z-values? Can I use qnorm(ppoints(data)) to do
