SpatStat: creating window from quadrats
Dear R-sig-geo list members, I'm using the SpatStat R packages for analysing patterns of wild boar damages, considered as my point pattern dataset. This dataset is quite large, covering almost whole Belgium. I would like to make my analysis by quadrats of 10x10km. I thus created quadrats covering my points dataset using quadrats function. There come my question. I would like to retain as my window, only the quadrats that contain damage points and remove the one that are empty. I have the feeling this question is trivial but I couldn't find any way to do that (apart from creating a grid shape in GIS, but would prefer not...). Thanks for your help, Regards, Kevin
