[R-sig-Geo] Need an algorithm

[Mark Andersen]

Many thanks for all the responses to my query regarding identifying 
simulated fire scars and computing their sizes. I received many helpful 
responses, and thankfully no unhelpful ones. It turns out that what I'm 
looking for is called a connected clusters algorithm, and is, as I 
suspected, well-known in percolation theory. Julian Burgos provided some 
code that will do what I need. My next decision will be whether to 
convert Julian's code to Matlab, or to convert my existing Matlab code to R.
Again, my thanks to all!
regards,
Mark A.
