Hi All, I've gotten a number of reports from users about gplots::heatmap.2 generating 'node stack overflow' errors. As it turns out, these errors originate in stats:::plotNode, and are triggered when it is passed a dendrogram that is too deeply nested.
While increasing the stack size (which is a compile-time option for byte coded functions) can allow a particular instance to succeed, a better solution would be to modify stats:::plotNode to use a recursive, rather than iterative algorithm. Anyone want to take this up as a programming challenge? -Greg ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
