This is overlay() in the sp package for SpatialPolygons and SpatialPoints,
and you will need to use the deldir package to provide polygons of bounded
rather than infinite area - see the thread refered to her
Just want to follow up from my earlier post
Since the voronoi polygon layer and the point layer share the same study area,
is there a way to do a 'spatial joint' such that I can find out the points fall
into which polygon?
And to have a dataset like the following:
Caseid xc yc voronoi.pol
Dear R-users,
I have a dataset with over 5000 pts and I know their x and y coordinates.
Based on the study area, I created 10 random points and used these points to
create voronoi to dissect the space.
genxy.vm<-voronoi.mosaic(genxy$x, genxy$y, duplicate="remove")
genxy.vp<-voronoi.polygons(gen
