Good morning!
I need to create a binary matrix with all node of a phylogenetic tree and the
presence of each taxo in their respective node.
Example:
require(ape)
y-read.tree(text=(E,((H,I)D,(F,G)C)B)A;)
y
plot(y, show.node=TRUE)
I need to create a binary matrix as follows:
A
Hi Vanderlei,
Try this which uses ape function prop.part():
temp-prop.part(tree)
X-matrix(0,nrow=length(tree$tip),ncol=length(temp),dimnames=list(tree$tip.label,tree$node.label))
for(i in 1:ncol(X)) X[temp[[i]],i]-1
