[R] Drawing a tree in R

[Severin Hacker]

Hi,

I've been trying to make use of the dendrogram class to plot a tree. However, 
my attempts have failed so far because I'm not sure how to build up the nested 
list. (where do I have to store the nodes?). The tree I want to be drawn is 
like this: in the form (node, left child,right child) (root,(n1,1,(n2,2,3)),4) 

If it is not easily possible to draw a tree with the help of the dendrogram 
class I'm open to any other method to draw a tree in R!!

Thanks!

-Severin

Severin,

Check out the R package ape for plotting phylogenetic trees.  

require(ape)
foo <- read.tree(text = "(root,(n1,1,(n2,2,3)),4);")
plot(foo)
