I'm often asked to explain what R is, and I find it easiest to answer that question by providing examples of how people have used R in practice. To make that task easier, I've just added a new category to the blog: applications. The applications category is intended to showcase applications of R to real-world problems. Any post that shows an interesting use of R, or about a new domain where R is used, will be tagged with this category (and old posts have already been added where appropriate). I'm always looking for interesting examples of R in action, so if you come across a neat application (or have done one yourself) please let me know.
