Re: [R-sig-phylo] Applying standard error in phylogenetic signal measurement using lambda

Hi Ting-Wen. If you could (off-list) send me the simplest possible reproducible example of the error (with your input data files or a saved R workspace) I would be more than happy to look into it. All the best, Liam Liam J. Revell, Associate Professor of Biology University of Massachusetts

Re: [R-sig-phylo] Graphically comparing multiple trees

Thank You! densityTree(trees, use.gradient=TRUE, fix.depth=TRUE, alpha=0.5, lwd=4) is really nice. Could You finally point me how to add supports (nodelabels) for each tree in its respective color? Sincerely, V. Dne středa 26. dubna 2017 22:10:27 CEST, Liam J. Revell napsal(a): > I have now

[R-sig-phylo] Applying standard error in phylogenetic signal measurement using lambda

Dear all, I’m measuring phylogenetic signal for a set of continuous traits using the function “phylosig”. I try to apply standard error of measurements in Pagel’s lambda, but the R gives this error message: 'Error in solve.default(V) : Lapack routine dgesv: system is exactly singular: U[1,1]
