Hello, everybody!
I have subscribed to the list only recently, although I've been actively
using R since February. I found it very useful and very flexible and I hope
to learn to use it better. My current problem concerns spatial statistics.
I need to partition a regular rectangular grid into given number of
subsets. For example for a 5*5 grid with 3 subsets I could have:
1 1 1 2 2
1 1 2 2 2
1 1 1 2 3
1 1 1 1 3
1 1 3 3 3
One of the things I have to take into account here is the neighborhood
matrix. I consider two cells neighbors if they have a common size (not
corner). Thus each cell in the middle of the grid has four neighbors.
Is there by any chance a ready package or function which does it in R? The
packages I found so far are for point processes. Also can anybody propose a
good algorithm for doing this?
Thanks a lot
