Hi,
I have a set of points.
I generated two different sets of ppp objets, each with a different window
(but same points)
The first window corresponds to the extent of the data, the second to the
administrative unit contour (polygonal window).
1. bastia.ppp is the first set of points.
2. bastia.ppp.polwin is the second.
I have applied dirichlet function to each of them and plotted it.
1. plot(dirichlet(bastia.ppp)) => gives me lines
2. plot(dirichlet(bastia.ppp.polwin)) => gives me coloured map.
Why do I get different plotting results?
Also, I don't notice differences in voronoi polygons contours between the
two sets. So does dirichlet take into account polygon windows or does it
always generate voronoi given a rectangular window?
Thanks in advance for the answer!
