generate the random pattern. Currently this must be a rectangular
window.FALSE, simulation is performed
in the window W, which must be rectangular.
If TRUE (the default), simulation is performed
on a larger window, and the result is clipped to the original
windnsim=1 and drop=TRUE (the default), the
result will be a point pattern, rather than a list
containing a point pattern.W
using a The Hardcore process is a model for strong spatial inhibition.
Two points of the process are forbidden to lie closer than
R units apart.
The Hardcore process is the special case of the Strauss process
(see rStrauss)
with interaction parameter $\gamma$ equal to zero.
The simulation algorithm used to generate the point pattern
is rmh, whose output
is only approximately correct).
There is a tiny chance that the algorithm will
run out of space before it has terminated. If this occurs, an error
message will be generated.
