Dear list, sorry for being late to the discussion. Thanks to the generous help of Iris Bardel-Kahr we are improving the vignettes for phangorn adding some more examples for morphological / complex / special traits. Please have a look at the vignettes on the github page https://klausvigo.github.io/phangorn/ in the articles section. The titles might change and sections still get moved around at the moment. So what you are interested in is distributed over several vignettes. And suggestions for improvement are welcome. In optim.pml() / pml_bb() you need to change the default value to optEdge=FALSE in case you only want to estimate the parameters for the rate matrix. Only time reversible models are possible at the moment. A parsimony analysis at the start might be useful. If the parsimony score divided by the number of sites is high, if you expect many state changes the ancestral reconstruction. At the root you will see a mixture of all states, which is a sign of uncertainty. This can also be an artefact if you observe transitions on short edges (so-called cherries) which will bias transition rates. However this you can catch if the number of expected substitutions is considerably higher than the parsimony score / site. Kind regards, Klaus
