Hi Nick, it might be useful to plot the node labels on the tree: plot(tree, label.offset = .25) tiplabels() nodelabels() Regards, Klaus On Tue, Sep 7, 2021 at 4:56 AM Emmanuel Paradis wrote: > Hi, > > A tree has n terminal nodes (aka tips) and m internal nodes (aka nodes > simply). In the

Hi, A tree has n terminal nodes (aka tips) and m internal nodes (aka nodes simply). In the edge matrix, the tips are numbered 1:n and the nodes are numbered (n+1):(n+m) (same than n+1:m). n and m can be found with: n <- Ntip(tree) # or length(tree$tip.label) m <- Nnode(tree) # or tree$Nnode

Hi Gustavo, I'm paleotree's author and maintainer. Just to be clear that I understand your problem, I believe you are saying that when you use timeSliceTree, you are getting an error that the internal call to dist.nodes is failing? Is that right? The first thought I have is that maybe the

Hi! I re-did chainsaw at some point, now there is chainsaw2. However, googling that gets you horror movies, so here is a link with example code: https://groups.google.com/d/msg/biogeobears/Jy9uYckOL7s/XuNZ0B3jAwAJ (the discussion there points out a rare case where this crashes, but for most
