Re: [R-sig-phylo] Counting and getting the age of cherries in a tree

Hi Ivan. Try this simple code: ## load packages library(phytools) library(phangorn) ## get tips descended from each node dd<-Descendants(tree,node=1:tree$Nnode+Ntip(tree),     type="tips") names(dd)<-1:tree$Nnode+Ntip(tree) ## get the NUMBER of tips from each node nn<-sapply(dd,length) ## get
