| SSI(spatial) | R Documentation |
Simulates SSI (sequential spatial inhibition) point process.
SSI(n, r)
n |
number of points |
r |
inhibition distance |
uses the region set by ppinit or ppregion.
list of vectors of x and y coordinates
Uses the random number generator.
will never return if r is too large and it cannot place n points
