If you aren't dedicated to an R specific solution, ImageJ is open source and does this under Analysis/Binary.

So for a connected patch of 27 pixels, all cells belonging to that patch will have a value of 27. Just wondering if anyone has any suggestions. Maybe a function I don't know about yet... Thanks in advance, Murray Richardson _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
