[R] how to write out a tree file with bootstrap from phangorn package

[Klaus Schliep]

Dear Jian-Feng,

you can use the function plotBS. plotBS plots a tree and adds the
support values (in %). This function also silently returns this tree:
tree <-  plotBS(fit$tree, bs)
# You can export than this tree using write.tree or write.nexus, e.g.
write.tree(tree)

Regards,
Klaus
