generate the random pattern. Currently this must be a rectangular

in the window W

on a larger window, and the result is clipped to the original

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

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.
