In recent phytools versions the phytools function describe.simmap returns an object of class "describe.simmap" which, if plotted, shows a phylogeny with posterior probabilities from stochastic mapping shown as pie charts at each node and tip of the tree. Unfortunately, when I switched the internal tree plotting function from ape's plot.phylo to plotTree in phytools, I made a mistake in setting the automatic offset of tip labels such that labels are frequently plotted outside the plotting window. This bug was reported to me today by a colleague and I just posted a new version of phytools with the bug in this plotting method fixed. This phytools version (>=0.4-26) can be downloaded from the phytools page and installed from source. Obviously, this fix will also be in subsequent CRAN releases of the phytools package.
