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 B C D
G 1 1 1 0
F 1 1 1 0
I 1 1 0 1
H 1 1 0 1
E 1 0 0 0
Somebody could help me to solve this problem.
Thanks,
Vanderlei Debastiani
