5:30 - 5:40  Meet & Greet and Big Hello J

5:40 - 6:15  KnitR 


James Stanley & Tak Ikeda, University of Otago, Wellington


Why might you want to integrate code and commentary with analysis outputs?

We’ll discuss some of the advantages of using knitr or Sweave to produce integrated output files (using R and LaTex commands) that contain the code for your analysis with the output woven through – plus “proper” document structure with commentary on data analysis issues, decisions that were made in approaching analysis, and other custom components.

The session will go through basics of getting your system set up for knitr/Sweave, examples of output documents, and some tips and tricks for getting the most out of these methods.    


Tak and James are biostatisticians at the University of Otago, Wellington, and work on the statistical aspects of a variety of research projects.
