[R] mclust - clustering by spatial patterns

[Jarrod Hadfield]

Dear All,

I have spatial data (presence/absence for 4000 squares) on 250 bird 
species and would like to use a model-based clustering technique to 
test for species associations.  Is there any way of passing a 
distance/correlation matrix to mclust as with hclust, rather than the 
actual data?  Or alternatively, is there a way of getting mclust to 
handle binary data?

I'd appreciate any suggestions!

Cheers,

Jarrod
