[R-sig-Geo] Regression kriging or kriging with external drift

2013-06-30 Thread Francesco Carotenuto

Hi, I am not very savvy with spatial data analysis (though I am doing my best to learn). I have embarked on a spatial analysis project and am not sure whether what I would like to do is possible. My dataset is over 500,000 points (with lat, long attributes as well as a single numerical

Hi LS, you can us function tess to create a tesselation and then split your ppp with it. See this example: data(lansing) lansing gridA- tess(xgrid=seq(0,1, by=0.1), ygrid=seq(0,1,by=0.1)) gridA plot(lansing) plot(gridA, add=T) lansing.g=split(lansing, gridA) lansing.g length(lansing.g)
