title: Proofreading the PDF of a book, thesis, or report derived from a large multi-file Sweave project
body: <p>I'm a big fan of reproducible research.
  I often use make, Sweave, LaTeX, and R to produce large research reports (i.e., lots of <code>Sexpr()</code> commands and heaps of graphs and tables).</p>
  
  <p>Obviously, <code>R CMD Sweave</code> identifies certain errors in the R code chunks at compilation.
  But the resulting PDF can still contain undesirable results.
  I have a few strategies for proofreading such documents, but I was interested in learning from  others on SO.</p>
