I've been playing around with the rgl package in the last week, as part of an ongoing quest to come up with nice-looking (but more importantly, useful) data vizualisations. It's a nice little package, and once you've run through the excell...

I recently read Ewan Birney's blog post, which I found echoed a lot of my own thoughts about the use of statistical in computational biology. I thought I would compile my own similar list but for bioinformatics / computational biology in general. I have not been and in the field as long as Ewan and I certainly still...

In short: R is a free intuitive programming language that is used by practitioners in a plethora of academic disciplines. Therefore, it is on the cutting edge, and expanding rapidly. It creates stunning visuals, works seamlessly together with LaTeX, has really good online documentation and the community is unparalleled. A week...

All posts in this series were combined into a single, extended tutorial and posted on my new blog.
