532 Spatial Point Patterns: Methodology and Applications with R
We ca n also simulate conditional on the configuration observed in a sub-window, that is, requir-
ing that, inside a specified sub-window V , the simulated pattern should agree with a specified po int
pattern y. To do this, set control$x.cond to equal the sp ecified point pattern y, making sure that
it is an object of class "ppp" and that the window Window(control$x.cond) is the conditioning
window V .
We can simulate conditional o n the presence of specified points, that is, requiring that the simu-
lated pattern should includ e a specified set of points. This is simulation from the Palm distribution of
the point process given a pattern y . To do this, set control$x.cond to be a data.frame ...
