[R] spatial outliers

[Monica Palaseanu-Lovejoy]

Hello everybody,

I have some questions about identifying spatial clustering in 
spatial autocorrelated data. It seems that there are some 
problems with the usual methods for cluster identification 
because they don’t take into consideration the spatial 
autocorrelation of data. 

I am wondering if there is any R procedure / packages which 
implement the OPTICS method? I am referring here to Ankerst 
et. al., 1999, OPTICS: Ordering Points to Identify the 
Clustering Structure, Proc. ACM SIGMOD’99 Int. Conf. On 
Management of Data, Philadelphia, PA, 
{ HYPERLINK "http://www.cs.ualberta.ca/~joerg/papers/OPTICS-final.pdf" }http://www.cs.ualberta.ca/~joerg/papers/OPTICS-final.pdf

Any help, as usual, is greatly appreciated,

Monica
