    ORIGINAL QUESTION: I m trying to find out if it s possible to perform a Ripley s K(t) analysis to determine spatial point pattern using a non-rectangular
    Message 1 of 1 , May 5, 1998
      I'm trying to find out if it's possible to perform a Ripley's K(t)
      analysis to determine spatial point pattern using a non-rectangular
      boundary. I can't seem to find a way to do this in S-PLUS (rectangular
      boundary required). Is there another software with which it is possible?

      Norm Finkelstein pointed me in the direction of Peter Diggle and Barry
      Rowlingson of Lancaster University in the UK. They wrote an add-on module
      for S-PLUS called SPLANCS that can perform the Ripley's K-function on
      odd-shaped boundaries. I've downloaded the program from
      but have not been able to get it to run on our system.

      This was the only response I received. I am assuming this type of point
      pattern analysis just isn't done (or rarely done) on non-rectangular
      boundaries. I've taken a subset of my data defined by a rectangular region
      to perform the analysis correctly.
