Hi Gopal.
I posted about this theme recently on my blog. For instance, here is one
solution for plotting a posterior distribution of changes of different
types from stochastic mapping:
http://blog.phytools.org/2016/10/testing-hypotheses-about-number-of.html;
and here is another example plotting the *entire* posterior sample of
changes onto the trees:
http://blog.phytools.org/2016/10/mapping-sampled-changes-on-tree-from.html.
You could also do the latter for any particular stochastic map history.
All the best, Liam

Dear list,
I am tracing evolution of a binary trait on a phylogeny with 1500 tips.
Since the trait is labile and scattered across the phylogeny (Fritz Purvis
D= 0.45), I find it difficult to visually count the number of gains/origin
of the trait in ancestral state reconstruction. Is there any function to
estimate the number of independent gains and the respective node number if
possible? I am currently mapping the trait using *simmap *function from
*phytools*.
Thanks in advance,
Gopal M
