Dear R-helpers, After putting my somewhat sparse (21 points) data into a 'ppp' format, I am unable to calculate the K function using Kest. I get the error "some 'x' not counted; maybe 'breaks' do not span range of 'x' ". So I tried to calculate the K function using the swedishpines dataset. Of course Kest(swedishpines) works fine but when i break it down to Kest(ppp (swedishpines$x,swedishpines$y)), I get the same spanning error. Has anyone else encountered this problem or knows how to get around it? Thank you. Traci Leong
