There were a couple of egregious bugs in kanova() that caused testing for interaction to give spurious results. These bugs have now been corrected. The corrected version, 0.3-20, is now on CRAN. The bugs *probably* have caused no harm, since testing for interaction (against an additive model) in the K-function context is unlikely to be of interest. cheers, Rolf Turner -- Honorary Research Fellow Department of Statistics University of Auckland Stats.
