Hi Cacau.
It depends what exactly you're going for. For instance, you can plot
trees that face each other using cophylo.plot in the ape package;
however, if you don't need links connecting tips in each tree, then you
could use par(mfrow) or layout instead.
For example:
require(phytools)
par(mfrow=c(1,2))
plotTree(tree)
plotTree(tree,direction="leftwards")
This will repeat the labels twice. If you don't want to do this, you
could try:
layout(matrix(1:3,1,3),widths=c(0.48,0.04,0.48))
## adjust widths depending on the size of your tip
## labels
plotTree(tree,ftype="off")
plot.new(); plot.window(xlim=c(-1,1),ylim=c(1,length(tree$tip.label)))
par(cex=1)
text(rep(0,length(tree$tip.label)),1:length(tree$tip.label),tree$tip.label)
plotTree(tree,ftype="off",direction="leftwards")
Obviously, at each step you can use functions like nodelabels() etc. to
add features to the two plotted trees.
If you decide to use phytools, you should probably first install the
latest (non-CRAN) version (http://www.phytools.org/nonstatic or
http://www.phytools.org/nonstatic/bin for binaries).
Let us know if this helps you get started.

Hi,
I am thinking about building a mirror tree like the one shown as
follows. Does anybody know how I should do it? Thanks!
