Dear Debarchana,

I think that you could check any of the good books about point patterns
that there are currently out there. Diggle (2003), for example,
describes what you ask and most of the examples in the book can be
reproduced using package Splancs. Check  manual page of function mse2d
and references (in Splancs) as well.
