Description
Simulates SSI (sequential spatial inhibition) point process.Details
uses the region set by ppinit or ppregion.Value
list of vectors of x and y coordinatesSide Effects
Uses the random number generator.WARNINGS
will never return if r is too large and it cannot place n pointsSee Also

towns <- ppinit("towns.dat")
par(pty="s")
plot(Kfn(towns, 10), type="b", xlab="distance", ylab="L(t)")
