Thanks, that's what my guess was since the help page doesn't say anything special about binary trees. My code should work in either case. In case anyone's interested, there's an example of a lattice/grid heatmap at http://dsarkar.fhcrc.org/R/heatmap/lattice-heatmap.pdf (the primary benefit for me is better control over aspect ratio). -Deepayan ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
