Hello everyone,
Newbie here. I'm looking for a way to generate random trees of N tips,
allowing multifurcations. My N would be 12, so it wouldn't be practical
(nor possible) to work with all the possible trees (cf. allFurcTrees). I'd
be happy with a set of 1000 trees, sampled equiprobably. I'd
Hi Eduardo.
You could try something like this:
randomFurcTrees-function(n,N=1){
foo-function(n){
t-di2multi(rtree(n,br=sample(c(0,1),
size=2*(n-2),replace=TRUE),rooted=FALSE))
t$edge.length-NULL
t
}
trees-if(N1) replicate(N,foo(12),simplify=FALSE) else foo(n)
if(N1)
One can sample from all possible rooted labeled histories by randomly
bifurcating lineages, and at the end assigning the names randomly to the
tips. Note that a labeled history is not the same as a tree topology.
One can sample randomly from all topologies of rooted bifurcating trees

Hi -
I am trying to generate a heat map to visualize my data; and am having
trouble. I think the issue is the format of my data.
I need the Dec_Val to be the color on the heat map, and the other variables
to be the X and Y (like OffAge and Brd_Sze). When i have tried to do this
in the past
