Re: [R] Convert filogenetic tree to binary matrix

Hi Ben, Thank you for your help. I did the same question in the r-sig-phylo mailing list. Liam Revell gave the following solution: 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 Vand

[R] Convert filogenetic tree to binary matrix

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
