[R-sig-Geo] splitting a map into areas by number of addresses

[Sven Schmiedel]

Dear list,

I have the following problem: I have around 1,000,000 addresses of a country 
and want now to split the area in artificial "administrative units" with 
exactly 1,000 addresses per unit.

As I did not find a direct way to do this, my idea was to chose randomly 1,000 
addresses, use the voronoi tessellation (from library PBSmapping) for these and 
look how many addresses are found in each piece this mosaic. However, the 
result is not stable and the number of addresses varies quite a lot from unit 
to unit.

Hence, I would like to know if there is a procedure/package that is 
incorporating a function that is able to do this splitting with a fixed number 
of addresses. If anyone has another program or an methodological approach to 
this problem I would be happy about this information.

Best wishes,

Sven Schmiedel
