R: Sweave Tutorials

Sweave provides a flexible framework for mixing text and S code for automatic report generation. The basic idea is to replace the S (or R) code with its output, such that the final document only contains the text and the output of the statistical analysis. It is great for automatic report generation and mixing word processing (text, or LaTeX) and R code, output and graphics. Here are some tutorials on Sweave:

From Jeromy Anglim (University of Melbourne):
Tutorial 1: Using Sweave, R, and Make to Generate a PDF of Multiple Choice Questions
Tutorial 2: Batch Individual Personality Reports using R, Sweave, and LaTeX
Tutorial 3: Console Input and Output - Multiple Choice Test Analysis
