R functions developed by Philip Dixon
DISCLAIMER:
Generally, these are research quality
programs. The only documentation is the set of inline comments.
They have been debugged, but I can not provide any guarantee of
correct calculation, application or interpretation.
Please send me an e-mail message if you find a problem.
These are poor examples of programming style. Some were
originally written in
Splus before objects and classes, so the interface is antiquated.
These functions require helper functions from a package of point
process functions. Either the splancs or spatstat package will work,
but this code uses splancs function names.
