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]
Hi Carmelo,
thank you so much for the suggestions. =)
All the best

(Aside from the points above, I am assuming that the 18 compounds do not
add up to 100% of the sample. If they do, then you would only want to
analyze 17 of them.)
Sincerely,

Dear all,
recently I got an error when downloading sequences in R using MacOS 10.12 (but
no problem when using WIndows 7). I was using the function read.GenBank in
package ape and pretty sure my laptop was connecting to the internet. Following
is how the error looks like:
R version 3.3.2
Dear all,
I would like to test for phylogenetic signal in a discrete trait with 3 states
(trait “str”) and another discrete trait with 7 states (trait “hab") using
Pagel’s lambda. I have tried to apply the function “fitDiscrete” in geiger to
my data, but not sure whether this is correct or
Dear experts,
I am new in the comparative phylogenetic methods. By reading papers, when there
is a term saying a trait is "phylogenetically labile”, does it mean that the
trait is phylogenetically “convergent", with similar values for species from
distantly related clades, or does it mean
