Hello,
I'm working in spatstat and having difficulty with the ppp objects. I can get a ppp object for one set of data, but with the same code applied to a second data set (all I am changing is the field identifier), I get the following error message:
Error in switch(w$type, rectangle={: internal error: some total scores are neither 0 nor 1
What is a "ppp object"? Which function has been applied and generated that error message?
The error message tells you some values a ought to sum up to 0 or 1 but they don't. I (and perhaps others as well) cannot help when you don't specify some relevant information.

Any thoughts on what this means and how to correct it would be most appreciated.
Thanks, Suzanne
