Relationship between instantaneous rate of change and global clock model?
... What is the relationship between the instantaneous rate of change in the rate matrix of continuous time Markov chain and the branch rate/clock rate in a global/strick clock model? For instance, in an F81 or GTR model of nucleotide substitution, should the individual instantaneous rates of change (e. ...

How do I evaluate a hypothesized correlation between the number of chromosomes and a phenotypic character?
... I am new to phylogenetic comparative methods and want to evaluate a hypothesis that proposes a link between the presence/absence of a phenotypic character with the number of chromosomes. I'm aware of models such as BiChrom, but what I want is the inverse. That is, these models evaluate hypotheses of ...

How do I annotate a tree with boostrap scores and color code clades in ggtree?
... I want to annotate a phylogenetic tree with bootstrap and add color to certain clades in ggtree. Something goes wrong when I try to do both, which has something to do with the indices of the internal nodes. Here is a random tree with 24 tips: library(ape) set.seed(123) rtree <- ...

How do I plot the posterior probability distribution of a particular node from a stochastic character map?
... I used `phytools` to create stochastic character maps of a discrete character from a set of 1000 phylogenetic trees. The function `describe.simmap` summarizes the results of these stochastic maps. This function yields as output the posterior probabilities of each node being in each state. What I wan ...

Is there a measure for degree of reticulation in a phylogenetic network?
... When working with phylogenetic networks, how does one talk about reticulate (i.e., web-like) the branches are? Is there a standard measure of this? If so, can someone recommend an R package that can calculate it? ...
