how to draw triangles with ggtree and ggplot.

Hi everyone, That’s the first tutorial I write, I will assume you know some basis of R. I try to write more to improve my writing for my PhD and for myself as English is not my native language. So please give me your feedback. The easiest way to contact me is via Twitter or via email. In this blog post I will start with a quick introduction to ggplot2, then show how to visualise a simple tree with ggtree1.
