I attended useR! 2012 this past summer and one of the highlights of the conference was a presentation by Yihui Xie and JJ Allaire on knitr. As an often frustrated user of Sweave, I was very impressed with how they streamlined the process of integrating R with LaTeX and other document types, and I was excited to take advantage of the tools. It also occurred to me that these tools, especially the simpler markdown language, could be useful to the students in my introductory statistics course.
