Hi all, I need some help with a warning message I've been getting when running parametric bootstrapping in OUwie.
>OUwie.boot(nboot=1, simmap.tree=F...) Beginning parametric bootstrap -- performing 1 replicates Warning: Some dates are negative? rootAge may be incorrectly defined or you are using a time-scaling method that warps the tree, like aba or zbla. Initializing... Finished. Begin thorough search... Finished. Summarizing results. Initially I didn't give it much thought, but my bootstrapping results are quite unexpected, and I'm starting to think that may be related to that warning. I don't get that warning when I run OUwie() with the same tree/dataset/settings, and I've been able to trace it to the function dateNodes in the package paleotree, but haven't been able to go any further than that. Thanks in advance for any help! *--* *Rafael Sobral Marcondes* PhD Candidate (Systematics, Ecology and Evolution/Ornithology) Museum of Natural Science <http://sites01.lsu.edu/wp/mns/> Louisiana State University 119 Foster Hall Baton Rouge, LA 70803, USA Twitter: @brown_birds <https://twitter.com/brown_birds> [[alternative HTML version deleted]] _______________________________________________ R-sig-phylo mailing list - Rfirstname.lastname@example.org https://stat.ethz.ch/mailman/listinfo/r-sig-phylo Searchable archive at http://email@example.com/
