What am I missing or doing wrong? The gstat manual at http://www.gstat.org/gstat.pdf says on p16 that "When no variograms are specified, inverse distance weighted interpolation is the default action (Fig. 2.1, example [6.3]). When variograms are specified the default prediction method is ordinary kriging Journel and Huijbregts (1978); Cressie (1993) (example [6.4] and example [6.8])."
