Hi,
I am working with a point pattern whose window is a spatial polygon which
describe the cost of Norway.
I need to get a smoother version of such polygon which wraps the original one.
I have tried to use the function
simplify.owin(my.owin,8)
but this does not work since some parts of
Hi Sara,
You can't avoid this when simplifying.
But you could find the window that results from the intersection from your
simplified one and the original with intersect.owin.
This window will not overlap the original one.

Hi Sara,
You can't avoid this when simplifying.
But you could find the window that results from the intersection from
bdist.points().
Maybe someone has a better suggestion on another way to do this
