R me hearties

One of the things we wanted to do with our data was create a tree of the species we have.
I immediately thought of using R, mainly because I took a course in basic R last semester and I keep hearing people sing it's praises.  Another reason for using R is that if you want to do something, chances are someone has already done it and posted the code for you.

I found a great example of creating phylogenies in R here.  The radial tree example below is what I'm aiming for although installing the right package has proved to be a little harder than expected.

At first glance it seemed as though there was a lot of stuff relating to R and creating phylogenies, however I soon discovered that this wasn't so.  Many of the R tutorials and examples do not help in building a tree from the data you have.
So the next task is to find a way to build the tree then play with it R.
