title: Is there a general manual for the R packages, "quantstrat","blotter","FinancialInstrument" etc. other than the function help files and demos?
body: <p>I'd like to learn how to use these packages, but I cannot seem to find any vignettes that offer something other than extensive code snippets. I'd like to learn about how they all fit together and something akin to a "walk through".</p>
  
  <p>I've found some examples on the web like this series: <a href="http://timelyportfolio.blogspot.com/2011/06/quantstrat-to-build-on.html" rel="nofollow noreferrer">http://timelyportfolio.blogspot.com/2011/06/quantstrat-to-build-on.html</a> but I'm after something a bit more in depth (like the vignettes / examples in the package "PerformanceAnalytics"</p>
  
  <p>Any sources?</p>
